The question Update: an agreement with Monica Cellio was given a historical lock yesterday.
According to the tag wiki for historical-lock,
A historical lock preserves older content that was very popular when it was originally posted, but is now off-topic or otherwise out of scope for the site it is posted on. Historically locking a post ends the debate over whether a question should be kept on the site or deleted, and is often the final state of a question that has been deleted and undeleted more than once.
I'm not sure how this applies to the post in question. The post is not a highly-popular older post that was on-topic when it was posted but that has become off-topic due to drift in Meta Stack Exchange's scope, it is recent post (<1 month old) that has been very unpopular (-1790 net score).
How does this question meet the criteria for a historical lock? Is there something better we can do with it?
To be clear, I'm not trying to restart debate on the underlying controversy that triggered the question, I'm just questioning the disposition of this particular question.
