I believe that the Distribute 0.6 branch is a stable continuation of
the setuptools (0.6) stable branch. Distribute 0.6 is intended to
include maintenance-only stable fixes (on the basis that setuptools no
longer provides even that minimal level of progress - something on
which I won't comment for fear of starting another long thread).
Distribute 0.7 is the development branch, looking at new features such
as Python 3 support.
The only other point you missed is that there is not universal
approval of setuptools as a solution to the packaging problem. Take-up
of setuptools (and eggs, and easy install, and the various other
aspects of the setuptools "ecosystem") is variable, with (as far as I
see it) strong support from the web development community, and mixed
reception elsewhere in the Python community.
