Do not underestimate the impact of fedora breakage.

Right. Shipping gcc-15.0.1 ten days before the official release (and then updating to gcc-15.1.1 immediately after the release) is really not a big deal. It would have made no practical difference if GCC had happened to release two weeks earlier, or F42 had been delayed a couple of weeks.

It's not like we radically change GCC just days before a new major release, breaking the ABI of all the packages that have been built with it up to that point.

The story here is Linus being cavalier about pushing without adequate testing, not fedora's policies which have been this way for years.
