It's the former, accidental overloading.  And it's not really an
attack, just an infidelity.  We did a lot to provide feedback
mechanisms where there was a risk of overload, and we missed this tiny
corner case.

As with the push policy stuff, the point is to avoid having a server
send pushes when the client doesn't really want them.

I agree on both counts.  I haven't been able to contrive anything that
works without ugly side-effects of one sort or other.  I'll probably
write a draft with a few ideas in it and see what people think when
confronted with specifics.
