--- Comment #9 from Eli Schwartz <eschwartz93 at gmail dot com> --- It's not a bad idea to "fix" it from both ends. Projects such as gegl cannot compile on macOS using GCC 13 or 14, and that's not going to change. They can't really know what versions their users have installed, so the only real choice to support this case is to do a configure probe. Not all projects will fix that, so the best that GCC can do is make those projects work with GCC 15. Also yes, that is such a lame flag naming convention...
