It looks like we have eliminated most (all?) of the unbounded dependencies on dev-lang/python from the gentoo repository, so this could actually work to satisfy the goal of smaller stages and only having one version of python installed. However, it feels like a step backward to me; I would rather treat python3 as the primary interpreter and python2 as the one necessary for the legacy baggage. I don't see any strong technical reason to switch from python2 + python3 to python2-only enabled. Some people don't like having two versions of python installed -- that's about the gist of it. So, I'm personally not going to make that change without some kind of vote on it. I can arrange a vote within the python team if you like.
