Fedora opens up to bundling

You didn't read the rest of the post did you? We support building against system versions, but requiring users to go and find 20 libraries (with dev environments…that all agree) on Windows is an undue burden for everyone involved. OS X isn't that different. So we ship the code ourselves with options to use your own copies (which Linux distros use).

These really are "system" libraries in the sense that they should be provided there (like OpenGL backends on Linux).

Yeah, but what about OpenSSL? Boost? Qt? Python? There's no standard place to put them that doesn't become hell once more than one app thinks they know how things are supposed to work gets it wrong. And the Windows store certainly isn't going to provide such things.
