[JDEV] Negative priority

[Magnus Henoch]

XMPP IM states in section 11.3 that a resource with a negative
priority will not receive message or presence stanzas.  What will
happen to those stanzas instead?

For example, if a client sets negative priority when the user is away,
will it receive notification of accumulated presence changes when it
sets a positive priority again, and similarly for messages?  Or is it
simply a bad idea to rely on such behavior?
