So, because at some undetermined point in the future it would be
smoother to migrate to python-3 as default this way, you want to
burden the great majority of users now with what is for all intents
and purposes to them a useless number of multiple, slotted python
versions?

I see that as a problem. For the great majority of users python:2.7 is
currently, and for the foreseeable future, the best choice. There is a
great number of packages and libraries that don't work with python-3,
and just a handful that don't work with python-2.

It also leads to all kinds of spurious bugs, such as people who have
2.7 set as their default interpreter, but have not removed and masked
>=3.0, so end up with updates, but forget to switch their py3
interpreter to the latest version.

Until such time this situation becomes radically different, we should
make sure users have the best experience, which is python:2.7 by
default, and python-3 only if they explicitly choose to install it.
