The objective is to reduce load for the release manager. Any kind of
release that is worth anything takes several hours to produce, in
my experience (if it could be made completely automatic, it wouldn't
be good, since glitches would not be detected).

I would like get Anthony's opinion on this aspect.

See PEP 101. A release involves many more steps, and it's not clear
whether a release candidate could be skipped.

I think we would need to restrict the total number of releases
made per year. The one-year limit may be debatable, and immediate
releases might be possible, as long as there is some provision
that releases are not made at a too-high rate.

I think OS distributors typically *do* use official tar balls, even
if they import them as a vendor branch somewhere. Also, creating the
tar ball is not the only activity: creating a new web page on
pydotorg, running the test suite, etc. all is still necessary.

In any case, the patch gets certified by being committed (with
the indication that it is a security fix), so if they want
certified patches, they can just import the maintenance branch.
