@tyil @baleine XMPP can be registration-free with SASL ANONYMOUS. I wish it was better supported.

@tyil @baleine For example, there are no mobile clients that support it and there are only a few server instances and MUCs that allow it, it seems.

If it were otherwise, I think that would suit both @baleine and @tyil.
