Ubuntu provides a (partial) Py3 port of boto. And I don't really see why
you would consider fabric a dependency that keeps you from switching to
Py3. In many cases, you can just keep running it in Py2 as you did before.

Taking a closer look at the "big list" that caniusepython3 spits out will
usually make it shrink to a manageable size. Meaning, the blind size of
that list is not an excuse for anything.
