Quorum queues do not support global QoS prefetch (as specified here), whereas as I understand SimpleAmqpClient always invokes QoS with global=true.

Indeed, when BasicConsume is called with default message_prefetch_count, I get an exception. However, when it is called with message_prefetch_count=0, it returns fine, and (what's more surprising) I can even later do seemingly successful BasicQos calls...

Can I rely on this behavior or/and is there a more proper way of dealing with QoS on Quorum queues?

(v.2.6.0, according to Version.h.)
