(set-language-for-mode 'foo-ts-mode 'foo)
Maybe we want to introduce this concept, indeed.
maybe we want to that notion of "language" from elsewhere, such as
the one used in LSP?
Please don't call it "language". That'd be confusing. LSP is about
programming languages, so "language" is natural there. But in Emacs,
a major mode is more general than that. For example, it is not
unthinkable to consider mail-mode to be the extra-parent of
message-mode (or vice versa) -- but what is the "language" in that
case?
Or maybe we want to take it from MIME types?
I'm sure there are other options out there.
Problem is: they come with their own complexities and corner cases.
After all, this is inevitable when you create a taxonomy.
IOW, while we*may* want to add support for an explicit notion of "file
type", it's a whole problem in itself and it will not solve all
our problems either.
File types also have problems: Emacs modes are sometimes defined for
buffers that don't visit files.
