I think time-machine is the tool to use here, and as Maxime suggested, 
if you really need to keep maintaining a python2 package than guix-past 
is the perfect place to do it (porting to python3 makes probably still 
more sense than maintaining an outdated python package).

I don't see the problem, python 2 was sunsetting in 2020(!) [1] after a 
prolongation from 2015, so it should not come as a surprise.
