Do we draw a line anywhere for history questions or are we not really concerned as long as they asking for the origin of some Japanese word or phrase?

Answer 1

I think they are appropriate.

Studying the history, the development of a language and the etymology of its words can be very useful sometimes to understand the language now.

Meanings can change, words can change, but learning the history and the origin can help you to have a wider view on the language, that's my opinion.
