Opening such files as plain text?

If we use a new file extension, I am 99% confident that this will happen
again, i.e. there will be tools (editors, especially) that will not
correctly "recognize" such files as containing C++ code.

(Note that this is the same issue I noted in my original reply to this
thread as a reason to avoid creating a new suffix unnecessarily, which
opened the discussion on said necessity.)
