> @magicus every "port" in OpenJDK is supposed to have a clear owner and support system. Zero has been somewhat lacking in that area but there were enough people to keep it surviving. Now I'm not so sure. Does Zero have an active user community? Developer community? If so they are the ones who need to assess this change.

FWIW, Zero had fallen into Red Hat hands for support. The official lead (if you look at Census) is Gary Benson, who is not active in this project anymore. Since then, it was mostly supported by RH folks (like me) with contributions from Debian, Tencent, Huawei, Alibaba -- mostly because all of us have arch ports that do not have full-blown Server VMs yet.

I have put things in motion to claim the leadership more formally. I do have to note, though, that over the last few years of me whipping Zero into shape, this is the first time anyone asked the formal governance question, which must tell us something about how much we care about ownership formalities here ;)
