Are there modes that can adapt to multiple different major modes for
language, but without knowing the details of the major mode?  I don't
know but it seems iffy to me.

Do you know many cases where this isn't true?

Its the usual case in company-mode backends, I think. E.g., company-clang only cares that the edited language is one from a given list, not about the current major mode. Same for third-party backends for JS, and company-css, of course.

There might be some problems about unknown major modes setting the syntax table to unreasonable values, but we could treat those as bugs in those major modes.

Anyway, my suggestion makes things more complex. I'm not seeing a lot of reaction to it, so maybe disregard for now. We could add some major-mode->language mapping later down the road.
