MSI is terrible. It has older tools, and maybe that's what you mean by mature, but every time I've ever interacted with an MSI build process, I walk away amazed that this is the actual, certified, Microsoft-approved way to package applications for the most popular OS in the world.
Furthermore, it's not really that great of a dependency tracking system, although in theory you can use it for that. Certainly nowhere near APT or RPM.
And on OS X, you've got a whole hodgepodge of competing solutions. Which one of those should the Python runtime rely on to quickly resolve packages and modules at import time?
