I certainly can't provide an authoritative answer to the question, but if it were me, unless there are important rdepends that might cause pandas to be kept if we end up not being able to completely ditch python2, I would drop the python-* package(s) and move on.  Transient support for things soon to be removed/updated isn't worth the trouble.

I haven't checked the rdepends, so I don't have any opinion about which case applies in this instance.
