Just because you report it as a bug doesn't mean the maintainers will
fix it or agree that it should be fixed.  There will sometimes be
overriding concerns.  I think the main 2 reasons why a C-to-C call
should not be replaced by a call "via Elisp" are:
- the call is made in a context where it's unsafe to run arbitrary Elisp
  code (e.g. GC is not allowed, or something like that).
- the performance cost would be too high compared to the benefit of the
  added flexibility.

So whether the code can be changed or not will depend on the
specific cases.  Hence report them as bugs and so the maintainers can
look into it.
