Aware of it, and not happy with it. Basically and with all respect to
the authors, it looks like an API that documents code behavior, not
code that implements a designed API.
I've just posted a lengthy proposal for a new SUB API. I should have,
but forgot to, cover this particular issue. Setting prefix criteria
should be idempotent (i.e. if done again, have no further effect).
You can do a workaround which is to explicitly UNSUBSCRIBE before
every SUBSCRIBE but apps should not have to do this.
