First, a few issues with your post:
Writing only answers questions about how to write, not what to write. I've seen one, maybe two questions properly migrated to Writing over the 7+ years I've been here. 99.999% of all the questions you think should be migrated there are actually off-topic there. There is no stack for "help me write my story" questions.
To the best of my knowledge, there is no way to "migrate" a question to the Chat room. I could be wrong about this. If so, one of the Mods will correct me, but I believe the only path for migrating a question to chat is to either close or delete the question and invite the OP to ask in Chat. That's primarily an action taken by the OP, not the moderators.
The meta question you linked to (and the question for which it was closed as a duplicate) has a standing score of -9. No answer to the question has value as the question itself has no support in a community that, when there is strong support (or strong rejection), has scores in the hundreds. A -9 is Meta.StackExchange-ese for "meh."
That link to Meta.Worldbuilding, curiously, is a question I answered. The question it links to is NOT an effort to convince Science Fiction & Fantasy mods to migrate. It was an effort to better understand OUR requirements so THEY could refine when they could migrate. This reflects @L.Dutch's answer to your question.
Now my answer
I appreciate your effort, but please understand that what you're really saying is that in the name of a kinder, more inviting space it shouldn't be the responsibility of new users to read the help center or the tour and follow the rules of this Stack.
It's a bit like saying the frustration and embarrassment of speeding tickets should be avoided even if the driver didn't read the driver's handbook or the sign indicating the limit.
It's certainly true that our increasingly angry and vociferous world is in need of compassion, kindness, and love. But the world is also in need of discipline, honor, and duty. Every society (real or online) has rules that are necessary for a variety of reasons. Here those reasons include the quality of the service we provide, fair and orderly processing of requests, and the hope that new users eventually become senior users who help moderate the site.
From that point of view, finding ways to avoid closing questions that require closing per the rules...:
- Is not a service to Stack Exchange, which wants to be the purveyor of quality answers to quality questions.
- Is not a service to our Stack, which wants questions that are on-topic.
- Is not a service to the OP, who needs to learn how to use the Stack.
VTCs, like C, D, and F grades in school, are a fact of life the OP must learn from. The choice to not understand who we are and how we work has (and should have) consequences. We try not to be mean-spirited about it (though the frustration sometimes peaks...) and speaking for my own part, if you click on those Help Center links I provide, they take you to the specific pages where the violated rule is explained. Which is better than a speeding ticket that will only tell you the violated ordinance number with the expectation that you, the ticket recipient, will take the time to look it up and understand it.
Most don't. They just pay the ticket and go on being bad drivers.
Stack Exchange is not and should not be a place where any old question can be answered. There are already services out there (quora, reddit, countless forums...) that embrace that madness. Stack Exchange was specifically designed (and here's the kicker) for educated people who have exhausted their research abilities to query experts for help with specific, well-focused, well-defined problems.
That makes a lot of sense when talking about the great-granddaddy Stack, Stack Overflow, which focuses on software. College-educated programmers can explain a specific problem they're having and experts with decades of experience can help them find a solution.
It's a bit more complex here at Worldbuilding where we regularly find high-school and early-college students who want to write Hard Science genre stories — but haven't yet gained the education to know how to even ask the question. And yet, like new 16-year-old drivers here in the U.S., are still expected to follow the rules.
So, no. Migration is not a good choice for the moderator's (or, by extension, the users who participate in site self-moderation) default action. @L.Dutch explained the basics of why it wouldn't work. I've explained why most questions you think could be migrated actually can't.
In the end, the best possible solution is and always will be for new users to acquaint themselves with the rules before using the site. And if that can't be expected, to learn quickly when they get their speeding ticket.
