It's a price to pay for proper encryption that works with multiple sessions🤷
XMPP crowd was making fun of Matrix for this, but that is just how Double Ratchet works — now it got implemented in popular XMPP clients and it turned out that it's even worse than it was in Matrix and before that it "just worked" simply because nothing was encrypted.

Leaking presence to the servers of participants of a multi-user room that I'm in is the thing I'm the least concerned about TBH, XMPP doesn't do it because the rooms aren't distributed and only exist on the server they were created on. A lot of people do not seem to understand this: XMPP doesn't have a more secure implementation of the feature — it simply doesn't have this feature at all.
