This sounds for the better. Not having code mirrors (as other distribution channels) sounds not just insecure, but borderly malicious.

I suspect you have no idea what AUR is and how it works and furthermore, you have no experience with software packaging.

If a project is using github to publish releases, where else are consumers of that software going to get them from?

Having all sources of everything that is packaged backed up is a must for the official repository of a competent distro, but even in that case there is no reason not to use github in normal operation.

Depends what you mean by better. It's kind of annoying for me when trying to install some software I want to actually use, and I just can't.
