"Broken" is an exaggeration.  C source files are less important that
Lisp sources, and in many cases the C sources are not installed at all
on the user's machine.  I see no problem here.

I didn't say it was bad, I said your suggestion for a change was not a
good idea, since it would introduce a problem where currently there is
none.

This problem doesn't exist for most users, so I see no reason to fix
something that isn't broken.
