Indeed, though it seems fairly simple compared to what is possible.
It should be feasible, for example, to do things like having a
language mode highlight errors (not just syntax errors but type
errors and the like) in real time, provide easy renaming of
identifiers across whole projects, provide smart completion, etc.

I'm also imagining features where you can request documentation for
any function or variable and it will pop up a formatted version of
the documentation comment, just like you can do for elisp today.

Especially if GCC and other Gnu tools gained Language Server
capabilities, this could provide a substantial win for programmers
using Emacs.
