I think the cloud instance is a pretty good option, and is effectively what the old-gangsta CentOS team was doing, with more or different steps. Back in the old days the RPMs were manually imported, there was no RH provided pipeline to get unbranded RPM sources. So it's really not a big deal to go back to the bad old ways, and if they want to ignore the new shiny CentOS stream way of things, well they are free to be as masochistic as they desire. Certainly nobody is forcing math students to use a graphing scientific calculator if they instead prefer to use a slide rule, because we sent men to the moon with slide rules... so I see no point in complaining about Linux neckbeards preferring to stay with the crufty old ways of importing package sources devoid of GIT history, or any modern pleasantries provided by CentOS Stream. I actually respect these rebuilders, although I think they are zealots to some extent, they are zealots in the good way, highly principled on the idea that software builds should be reproducible, for the sake of validating the software supply chain. But there is an insidious side, their user community is not aligned with the noble ideals of rebuilds, and tend to want the value without the costs. It's one thing to rebuild packages, and another to spin a compose of those rebuilt packages into a distro. That's what RH is apparently all bothered about, and I cannot blame them to some extent. But that said, the user community around the foot hills is still the RH user community for them all the way up high on mount Olympus. So I think Rocky, Alma, or whoever else will still get the package sources, no biggy. But what I wonder about is how RH will treat subscribers who deploy RH and the rebuilds.
