> So this then becomes a question of deciding when publishing is "too slow", and being able to continue

I think conceptually it's different - it's a matter of is the broker running "normally" albeit really slowly (that's ok, we'll live with it) or has the broker said "Enough!" and sent a flow control message. That ought to be a detectable condition, and is fundamentally different to a broker simply crawling to a halt.
