If you wanted to look at #32163 and have a way to get stricter on warnings without solving all at once would certainly welcome it. Achievable through various GCC flags I think

@WillAyd You think it's possible to have the -Werror flag only for specific files? (to prevent regression to fixed files)

[WillAyd]

i was thinking individual warnings but sure to individual files if not overly complicated. There’s only a few left outside of that PR
