Hellz yeah. I'm at ~10 active users on my XMPP server and going strong. Finally something that won't unilaterally lock us out if we don't update every week, and we can chat from using any OS. We really do not care about "reactions" or stickers or all that other shit people complain about being lacking. "It doesn't look nice enough".. We just want to talk in private with a secure protocol that lets us actually use whatever we have, up to and including no mobile device at all.
