I don’t know about that, though. If you think from the perspective of how the different distros relate to each other - Tumbleweed → SLE → Leap is the progression.
With OBS, I don’t think it makes sense to rebrand that - it’s an openSUSE Project, but it is able to be used by any distro, really. The same holds true for things like kiwi.
I found the talk from the conference to be very illuminating from a structural perspective. Definitely worth watching to get a clearer picture of how things fit together.
