Today someone had asked a question on the meta site, which was actually a question on mathematics.
It was migrated, correctly, to the main site. There it was closed for lack of context. Being a migrated question, upon closure the question was locked and the migrated copy was "closed as off topic", which just seems a bit strange.
Now, I'm not advocating that we should be more careful when closing migrated questions. But now the process of correcting the question is essentially to delete the one from the meta site and post a new one of the main site (or ask for the question to be explicitly unlocked and/or reopened).
Sure, this might happen once in a sufficiently long time for it to be a non-issue. But why does it happen at all? I doubt anything anywhere on the SE network was migrated from a meta site to its main site, without being a question accidentally asked on the meta site in the first place.
Is it possible that a question migrated from the meta site will be exempt from the usual "rejected migration" process?
