That's what the autoplug-continue is used for. playbin2 checks (should check)
if the sink supports the caps and tell decodebin2 to stop autoplugging in that
case.

That's a bug in your sink then, decodebin2/uridecodebin must not autoplug sinks
and will not autoplug sinks unless they have the wrong classification in the
element details (does your sink say it's a Decoder or Parser or Demuxer or
Depayloader? If it does: that's the problem)

> va element only works if the hardware supports the required features.

Does that mean, that changing the state of those elements to READY will fail?
Or will the elements fail later? If they fail later that's a problem for
autoplugging (e.g. if you have the va elements on hardware that doesn't support
va).
