You can use the latter to do extra, periodic checks that the

 People are never going to take you seriously as long as
you keep offering what are obviously strawman arguments,
and especially ones where you know better but pretend
that you don't.

You've perhaps missed my main point, which was that gcc 14 now reports hard errors BY DEFAULT for things which I have argued in the past should be hard errors by default.
You've probably also missed my secondary point, which was asking WHY that change was made, since all that people had to do to get that behaviour was to jump through a number of hoops as I've always been told to do. Apparently that was not good enough!
I've also learnt something interesting. Which is that whatever the current version of gcc does is always right, and I'm always wrong if I suggest it should be any different.
But if gcc suddenly starts doing what I'd advocated, then according to you I'm still wrong! So I can never win.
