The point about CI is super strong; GitHub Actions almost made me quit being a programmer and I've been doing things professionally ever since Winter 2001.
I don't think much of Drew DeVault -- whether I agree with him or not is not at all relevant to any decision of using his products IMO -- but I'll vote with all three hands for a better and more seamless CI!
I was not aware of that aspect of SourceHut so now I'll seriously consider it.
