> exclusive yes i think would have similar issue, after all it followed
the same logic of message groups in part. It would be easy to fix, as in the
same place / if statement just check for the exclusive flag.
Nice, I suppose that would be better to raise a different issue/PR for that
even if I'm tempted to do it fro this one: it is indeed fixing a similar but
different issue.
I'm anyway opened to do it differently too :+1:

would still spin i assume.
I the message group isn't assigned it will use round robin between the
consumers until noDeliver == size: in that case it will stop spinning without
burning any CPU, because deliverAsync won't be called anymore.
