The XMPP Extensions Editor has received a proposal for
a new XEP.
Title: Explicit Mentions
Abstract:
This specification defines a way to explicitly mention a person or
groups of people.
URL: https://xmpp.org/extensions/inbox/explicit-mentions.html
The Council will decide in the next two weeks whether to accept this
proposal as an official XEP.

Thanks for taking over and making this a thing :)
A few notes/nits,
- The jid attribute
Same as singpolyma, I would settle on requiring occupant-id I think for
all types of rooms, makes the whole thing simpler, and rooms without it
are scarce nowadays (at least in places that matter).
I also did include a note about this in implementation notes.
Anonymous unique occupant identifiers for MUCs
(XEP-0421) [3] is being used to mention in Multi-User Chat (XEP-0045) [1] instead of a
participant JID or a real JID. This allows us to have a common solution across MUC, and
also to use a stable identifier, that is guaranteed to be unique per occupant (bare JID)
and prevent usurpation.
- The noping modifier
To me the purpose of the spec is to make mentions explicit. Thus
changing the status-quo and making the non-usage of this spec "not" a
mention, which would make the modifier redundant and confusing
(mentioning not to mention).
This somewhat conflicts with implementation notes:
Implementations SHOULD also allow sending participants
to talk about someone without having to mention them.
Might be useful as a temporary measure but I certainly wouldn't want
that to stick around.
