Fine, perhaps I'm nitpicking the fact. F42 made an unreleased compiler
their default, so it is technically "released".

Yes, I understand that, but you didn't coordinate with anyone. You
didn't search lore for the warning strings, you didn't even check -next
where you've now created merge conflicts. You put insufficiently tested
patches into the tree at the last minute and cut an rc release that broke
for everyone using GCC <15. You mercilessly flame maintainers for much
much less.

Why make compiler version upgrades a surprise? I'm hardly the only person
who was working to make the GCC 15 transition smooth. This made more
work for people, wasted your time to recreate existing patches, and broke
the build. I am hardly being unreasonable in asking you to do better.
