The problem is that in the python ecosystem there really isn't a default de facto standard yet at all. It's supposed to be pip, but enough people dislike pip that it's hard as a newcomer to know if it's actually the standard or not.
The nice thing about putting something like this on a pedestal is that maybe it could actually become a standard, even if the standard should be simple and get out of the way. Better to have a standard that's a bit over the top than no standard at all.
