If i was the only maintainer of the package in debian, i would at least
orphan it. But, more likely, i think i would request removal from
debian, as the upstream maintenance efforts appear to be unsustainable.
I don't think it would be responsible to ship it in Bullseye.
But Christoph, i leave those choices up to you. If you do any of the
above, please Cc me on it. I'm also happy to be named as an
(ir?)responsible party in the event that it does go away from debian.
I really appreciate all the effort, goodwill, resources, time, and
energy that folks have put into SKS on behalf of the OpenPGP ecosystem
for years, and i hope that we can funnel some fraction of that energy
into projects that are more sustainable and useful for the OpenPGP
ecosystem going forward.
