I believe the answers to some of these questions are in GHA workflow history:

Yes, systems-wise with GHA, we are in somewhat awkward position to trust that GH Cloud (Azure?) is 
configured correctly, runs on proper hardware, and is being maintained. There is a fair amount of 
trust in this equation. I haven't seen that trust broken in the last half a year the GHA were 
running for OpenJDK (both for mainline JDK and Codetools projects), so I am keeping hopeful.

The fact that GHA is not ideal does not make it less useful. As I note in the reply to Mark, the 
number of follow-up trivial build/test fixes had dropped palpably after GHA were introduced in JDK 
mainline repo.

Again, at present this seems to be the self-appointed duty of some OpenJDK contributors, look at GHA 
workflow history. If the only thing missing here is formal assignment to maintain this, we can solve 
that. I am not sure that is a problem worth solving, though, based on our current experience: there 
are interested parties that do that outside the formal assignment.
