These questions, definitely fit this criteria:

• Does this question match the criteria provided in the Stack Overflow FAQ?

Yeap, hidden features are not subjective ( the hiddenability might be - in which case it would receive a downvote - but the feature is not)

• Is this question accepted by the community, as reflected in upvotes, favorites, views, and answers?

Definitely

• Does this question teach me anything that could make me better at my job? Can I learn something from it?

I learn a couple of new things in the process. Either to avoid them, like corner cases, or to use better the language.

They should stay.
