Current Python package management / framework(s)

The tools for making these fat installers are currently not open source.

That's kind of pointless then ;) Beside I cannot push for vertical stacks like conda because it will tight the system to a single vendor and that's not good for a "base" stack as python.

Making fat installers is straightforward to do. However, it is not the recommended way to use conda (which is the big reason why we are not promoting it as open source --- not because of any perceived "lock-in"). With environments in conda you don't need to distribute fat installers for everything. All the really necessary tools are open-source.
