I agree that the solution is not perfect for everybody, and if
I had one that would not be without problem, I would have adopted it.

Well, that's not satisfying from a rpm pov, unfortunately. 
But with some patchs, that the one that I would use, yes. 
until that, i prefer know documented breakage, than new undocumented breakage.
(ie, shadok proverb, if you want to have less unhappy people, just hit always the
same ).

I as more speaking of the transition from pyton 2 to python 3. I think the easiest
on a policy point of view is to handle this like 2 separate languages, but that mean twice the work.
And so we should at least try to  do better ( not sure that we can, of course ).
