[Standards] Re: XEP-0440 and tls-server-end-point

Dear all, coincidentally I was implementing `tls-server-end-point` channel binding for go-sendxmpp this morning. As a client can choose the method to use I don't see an issue here. I just prefer `tls-exporter` if TLSv1.3 is used and `tls-unique` otherwise and only use `tls-server-end-point` when it's the only method offered. As Holger and Andrzej pointed out there might be cases where the better methods are not available and using a weaker one is still better than no channel binding at all. Best regards, Martin
