Can you elaborate a bit more on this? I don't think anybody has
proposed links with their own internal state before in the qdev/qom
discussions...
Also a good solid use case for a bidirectional link is worth
discussing because it influences whether we want to make all
links bidi-by-default or try to do it as a special case.
(OTOH your argument does hold for why reset should be two-phase.)
thanks
