I think the idea of smaller and more frequent feature branches is a great idea: less code changes coming to master to review at once (compared to big core-updates merges), substitutes and closer to master to be easier for people to pull the branch and test, and some areas despite the number of builds would work nicely as a branch than just pushed (and lingering) into core-updates for much later.

I agree with all your points. We used to work this way back in the day
when there weren't very many Guix packages. There was always a
'core-updates' job, but if it was limited to packages that truly are
"core". Then, for several years, the build farm was underpowered
relative to the number of packages and it became impractical. I think we
are past that now.

I've attached a couple patches to get started but I need help getting
them to work.

There is 'etc/go-manifest.scm', which does work with `guix package -m
etc/go-manifest.scm --dry-run`.

And there is a diff for 'build-aux/cuirass/evaluate.scm', so that I can
test it with `make cuirass-jobs`.

But, `make cuirass-jobs` crashes with this manifest and I don't know
why:
