You either just strip down the functionality of the previous package to
something lean enough but having the typical functionality you think
most users will need _or_ you obsolete the previous package and then
have a bunch of new packages that do whatever you want.  The obsoletion
needs to name a suggested replacement.

Keep in mind that setup currently gives no hints on such optional
dependencies and when they are needed.

No, in part because there is no way for setup to ask the user and use
the answer.  The libsolv that does the actual package selection could do
that, but we don't deliver the inputs.
