Correct. It can (will be able to) talk to npm, pip, RubyGems, cpan, the full gamut of package providers. Connecting to things like Windows Update, Microsoft Dev Center, etc. are also possible to implement.
What a complete wasted effort it has become. It could have been so much more. Plus it scared Steam so much that we now have Steam OS and have over 1200 Linux games now available.
From what I understand, it's more of a "package manager-manager" so it manages other systems (like Chocolatey) rather than running the repos itself.
