https://superuser.com/q/1090890/31983 became a Hot Network Question, and I answered it, before I noticed that it might actually be off-topic. According to the Help Center, questions about programming are explicitly off-topic for Super User.
Is an abstract question about compiler bootstrapping out of scope for Super User? A moderator encouraged me to raise this question on Meta.
If it is off-topic, where should it be migrated?
