Seconded: https://bugs.launchpad.net/zc.buildout/+bug/190260

AFAIK, no.

No, since those are specific to a particular project and shouldn't be
shared.

(Actually, I don't understand what 'develop-eggs' is for, other than

echo 'bin parts develop-eggs' > .csvignore
svn propedit svn:ignore .
bzr ignore bin parts develop-eggs
or the equivalent for the VCS of your choice.
