Hi,

‘guix pack -RR’ produces package variants that can lead to profile
collision in the presence of propagated inputs:

$ guix pack -RR python-scipy python-numpy --no-grafts
guix pack: error: profile contains conflicting entries for python-numpy
guix pack: error:   first entry: python-numpy <at> 1.17.3 /gnu/store/603imkkh2bqs01z8ik0b2ndgpdz0jghk-python-numpy-1.17.3
guix pack: error:    ... propagated from python-scipy <at> 1.3.2

hint: Try upgrading both `python-scipy' and `python-numpy', or remove one of them from the profile.

Here the “R” variant conflicts with the regular one.
