Yes, my solution takes time. So does setting up a gated community and
making it work.
Meanwhile using explicit 'versions' over a URL in buildout.cfg is a
good enough hack to make it work with the cheeseshop today.

You don't get conflicts if you use 'or'. You just get different
preferred versions. The outer package wins, so Grok would win if that
includes the other component. If it wants to delegate this to the
other component it shouldn't specify a preferred version.

This is all very nice, but a gated community *don't solve my problem*.
I want to be able to release something, and then have people install
it with the same dependencies, and this should *never* break. A gated
community will *still* feature botched new releases, upgrades to 3.5
packages that suddenly get pulled in by my package, etc. You could do
this if you have a community *per project*, and the maintenance
overhead goes through the roof. I want to use my 'python setup.py
It also yet again introduces pulls us into our own community next to
the Python community, just as we started to engage with the
cheeseshop. I think that would be a very regrettable development and
I'm very much against it.
