 I think you can go with something very close to this design _if_ you
always have a product. This would mean that even a minimal Fedora
install would need a system-release-minimal, or whatever. Then all the
product subpackages can use the "least requires wins" method of compare
providers to make it work (the above is said without any testing).
 You can keep all the conflicts, but they are more like asserts than
something used to help pick the correct subpackage, currently.

 I don't see how weak deps. will solve any of your problems. If dnf
+rpmbuild+createrepo/etc also has support for the planned _rich_ deps.
then you should be able to do something like:

 Require: config-server      if system-release-server (is installed)
 Require: config-workstation if system-release-workstation (is installed)

...which is what you are trying to express. Also DNF should be better
able to handle the conflicts with backtracking too, so there's that.
