Indeed, build systems and compilers may not care much. However, editors
almost certainly will. (At minimum, syntax highlighting data will need
to be updated.) So will MIME types databases. It may be worth keeping in
mind that not only things like editors will change, but also any library
or program (e.g. `file`) that tries to produce a "file type" designation
for a file.

That being the case, there may indeed be an argument to be made against
introducing a new extension unnecessarily.
