This question should have been automatically deleted by the system as it meets all of the criteria listed in the help page. However, as the question was migrated from another site, the question is not being deleted due to a bug. Basically, there's a code optimization that prevents questions that were originally migrated from other sites from being deleted by most of the Roomba scripts, including the one in question here. This optimization is based on an assumption that was true at the time, but is no longer true due to recent feature changes (more info in footnote).
I was about to flag the question for deletion citing the bug and the fact that it should have been automatically deleted had it not been for the bug, but I figured I should instead start a discussion here and allow the community to decide whether the question should be deleted or not. The point of the deletion criteria in general is to remove questions that aren't useful additions to the site and to reduce clutter in search results for users searching for answers; perhaps this question might be a useful addition with some curation.
More information: in the past, all questions that were migrated from other sites and later closed would be marked as "rejected migrations" and would thus be locked, and locked questions were excluded from the affected Roomba criteria. Because it was safe to assume that a closed question that was migrated from another site would also be locked, this code optimization was implemented, perhaps because querying for a question's locked status would take more time. However, in June 2019, the system was changed to no longer mark migrated questions as "rejected" if they were closed a long time after they were migrated; this meant that closing migrated questions wouldn't always lock them, and so we end up with the now no longer true assumption.
