Another question: i see that this was merged recently by Dele https://github.com/igniterealtime/Openfire/pull/48
But i don't remember anything about it in the forums, nor a ticket in JIRA for this.
I did see a discussion at some point about it, but can't find it again for reference. In any case, it is an excellent piece of work and completements the User service plugin. It has minimium impact because it is an optional plugin. For completeness and for tracking especially on the next release note, I will raise a Jira ticket.
