Neither am I btw. Naming is hard, but it shouldn't be
_this_ hard.

I think editors where you can't write emails, list processes
or chat in IRC do use "language" or "file format" In Emacs,
it'd make sense to me to give this to at least those modes
derived from prog-mode also maybe some more (org, markdown, etc).
Other modes would return nil to mean "nope, not a language per 
se"

But if "language" or "file format" is still contentious, browser's
use of "content type" seems adequate.  Browsers don't always
server files after all.  Then probably the new getter would
return non-nil in even more modes, and  coverage would keep
growing to theoretically 100%.
