Someone would need to create appropriate batches and feed them to
wanna-build. Last time that was done by Jakub. Also, this means
(AFAIUI) that using python2.7 isn't really supported unless that is
Also, while doing so, one needs to make sure to not block an ongoing
transition, i.e. only schedule packages which are the same in testing
Some of the packages are arch-all and need (at least as of now) real
NMUs to get updated.

Looking only at these packages, the can be removed from testing (plus
gozerbot-plugins), so that doesn't sound too bad.

As we want to get rid of python2.5, that sounds like an candidate for
an removal bug even as of now.

In sum, sounds good to me as soon as someone volunteers to create
appropriate batches for the rebuilds.
