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.
