I have checked further, cups-browsed indeed does not update queues on
Bonjour record changes, the update to https is triggered by a completely
new Bonjour broadcast.

I have also tried to switch a printer on my server between accepting and
rejecting state, and this does not make CUPS/Avahi generating an update
of the Bonjour record (= sending a broadcast), avahi-discover on a
client did not show any evidence of a signal broadcasted because of this
change. Can this be a bug in CUPS which we should report?
