An awful lot of people are repeating this as if it's a solution
without understanding the existing architecture. Believe it or not,
attempting to abandon default streams and go back to only non-modular
content available by default is a lot harder than it sounds (or should
be, but I noted that we're working on that in another reply elsewhere
in the thread). There is currently no path to upgrades that would get
back from the modular versions and the closest we could manage would
be to rely on the dist-upgrade distro-sync, but in that case we
*still* need to have DNF recognize that the default stream has changed
(in this case, been dropped) and handle that accordingly.
It may be more work to go backwards than forwards at this point.
Modularity does provide some useful feature additions, so to my mind
it makes more sense to properly fix the issues we have with it rather
than expend enormous amounts of energy to remove those features and
revert to the old way of doing things. And, yes, reduce Fedora's value
to Red Hat in the process.
I started this discussion to ask the community to help us identify the
best path *forward*. An endless barrage of "kill it off" replies is
not helpful or productive. If anyone has specific advice on how to
move forward (or, indeed, if you can figure out how to migrate back
without considerable release engineering and packager effort), that
would be productive. Just please keep in mind that we have to go to
war with the army we have, not the one we wish we had.
That's just oversimplified - if you find that the way you are on is the wrong one just moving forward is not necessary the correct thing to do.
Going backwards to get a saner state is a worthwhile thing to do. I have yet to see an argument how replacing existing packages with modules or providing default streams by default helps to reach the objective of 'parallel availability' - by dropping the default modules by default you get pretty much that without the downsides.
