I see the problem you are describing, but how do you solve it currently?

That said, I *think* I could autogenerate Provides for pythonX.Ydist(M)
and pythonXdist(M), while only having requires generated
with pythonX.Ydist(M). Would that solve the problem while allowing
BuildRequires using pythonXdist(M) to pick up the latest one? I'm not
entirely sure it would...
