In practice it'd probably end up like the sources.list in Debian. E.g., an enormous number of users just use whatever pasta is copied in there by default. Then special devs change it or copypaste a Debian spell to magically add repos for whatever special cases they have.

And let's be honest-- if someone on HN were to post, "OMG the security updates repo got DDOS'd in Debian" it's not like the entire comment section is going to be filled with confused responses like, "Wait, do you mean the security updates for the gitlab repo that I added for my gitlab instance, or Debian's security repo for Debian the Universal Operating System?"
