Yes, I think we should document the expectations more clearly. I asked
on workflows@ if others already have docs.

For DCCP specifically I think we'd like to see some effort around
improving syzbot testing and addressing the bugs?

Right, in theory maintenance of the code already upstream is orthogonal
