I'm not very enthusiastic about this change.
Fedora maintainers can largely ignore ELN right now, because if stuff
works in rawhide, it will generally work in ELN, and someone else is
taking care of ELN builds.
New GCC releases almost always trigger new compile warnings or bugs
in code. So by pushing GCC 11 into ELN, it feels like we're making
it much more likely that ELN builds will fail, and now Fedora
maintainers have to debug ELN specific problems that won't reproduce
in rawhide branches :-(
Expectations for Fedora maintainers does not change.
ELN is a development playground. Think about sidetag, with slightly
better automation around it.
We provide ELN as the opportunity, option to play with early releases
of the GCC11 on the side. We are not requiring Fedora maintainers to
participate, we are inviting people who may be interested in this
work.
Now rawhide will be the latest stream, except for when it is not
the latest stream :-(
Fedora Rawhide is the latest stream of Fedora.
This doesn't contradict to the fact that certain "heavy" changes can
be tested in the sidetag or copr repositories before landing in
Rawhide. This is the usual practice for many subprojects, from desktop
to Python.
We are not moving the usual gcc11-related work from Rawhide into ELN,
we are adding the preliminary step to it.
