What issues I have in mind?
1. Fedora system upgrade (libgit2, axa, bat)
I guess this is about changing platform stream without rebuilding
modules. I.e. once relengs create Fedora 32 compose, no modules (except
of virtual "platform") can be installed because they require previous
platform:31.
How it works in classical Fedora? Relengs take Fedora 31 content and
copy it into Fedora 32 repository. And suddenly you have packages
for Fedora 32.
How it could workd in modular Fedora? Relengs take Fedora 31 content
including modules and copy it into Fedora 32 repository. Then they take
modulemd data and rewrite all modular dependencies from platform:31 to
platform:32. Voila, you have modules for Fedora 32. These modulemds
should be imported into MBS to be available at build-time. We don't have
to rebuild the modules because identical packages can belong to more
module builds.
