Petr and Daniel, thanks a lot for your replies. I hope some of mentioned limitations could be reflected in the modularity documentation. I read through most of it (including the drafts for f33 change) and I don't feel that the consequences of adding package to the module are clearly communicated.
And maybe something could be added to the modulemd spec to reflect that
the specific package is no longer required starting from release x. I
don't expect that to work from updates-modular for branched releases,
but having the ability to drop packages from module on a development
release would be awesome.
