Thanks for the explanations. I was actually under the impression for some reason that Factory is the base packages (thinking about factory images), rather than experimental ones. I've now disabled factory repos on our systems. I did notice that http://download.opensuse.org/repositories/devel:/languages:/python:/Factory/openSUSE_Leap_15.1/ was put live, but yeah, won't use it. Now to figure out why http://download.opensuse.org/pub/opensuse/repositories/Apache/ doesn't have 15.1 yet...
