Yes, that sounds like a good plan. With the long-term goal of moving
python2 itself to guix-past, if it ever ceases to be an important
dependency (which I am not yet convinced of).

These and more: once they are removed, there will be a new set of leaf
packages.

It might be worth checking if there is a Python 3 equivalent before
removing a library. But in the majority of cases there is.

It certainly makes sense to remove broken packages, but for the rest I'd
say guix-past is a better destination than the trashcan.
