Is there a cleanup effort on old questions going on? Today I got a comment out of the blue on a question I asked five years ago. This stack was a very different place then, and the question would be too broad if I asked it today. But it was relatively well received when I asked it, got some good answers, and the world moved on.
Today I got a comment and a close vote saying it was way too broad. Strange, but whatever. Then another comment showed up asking (probably rhetorically) why all these old questions are showing up in the review queue. This indicates to me that there's more than one of these older questions being flagged for closure, though I don't have access to the review queues myself to confirm.
So I figured I should ask -- is there a cleanup going on? Is there a discussion somewhere about this, about which questions should be closed as "too broad" by today's standards and which should have a 'historical lock' applied like we do on other stacks?
