I already replied to this, but let me point out why I think such a gated 
community would not be *sufficient* for my purposes.

I want to be able to release package X, and have a way for other people 
to install it and it not break, ever. This can be done with hard version 
numbers in install_requires today, but people object to this reasonably 
as it would reduce flexibility of component reuse. If we want to have a 
way to reproduce installations *exactly* and we want to still allow 
flexibility, a gated community while hopefully increasing the quality of 
individual releases still won't guarantee that package X won't break 
when someone else tries to install it.

Regards,

Martijn
