I'd like to propose we make use of the existing structure of SE for sandbox questions instead of artificially putting them inside Meta. I've not been able to find a previous discussion about this although I have searched.
Currently there seems to be a lot of admin to maintain it as part of Meta. This is because we are going against the grain of how the system works.
Allow questions such as "Here is my proposed question - how can I improve it for submission?"
Although answers may rely on opinion somewhat, answering could be restricted to people with substantial reputation.
Suggestion 1. Open a new stack (is that the right term?) in addition to Meta, that allows you to ask questions and has a discussion tag just like Meta does.
Suggestion 2. Put questions on the main Worldbuildng site and have a Sandbox tag.
The question will be phrased, "Here is my proposed question, how can I improve it?"
This way the SE structure is being used exactly as intended, i.e. question and answer.
Is this doable? If not what are the reasons?
