I wouldn't think that the Copts have this either, though I'm certainly no authority. Last weekend a man came to liturgy who apparently used to be there before I started attending, and everyone was just happy to see him. There were no questions as to where he'd been (and I couldn't make out what had happened, since he spoke only in Arabic). I guess he knew abouna personally, though, so maybe that's part of it. Maybe they spoke beforehand or something.
Still, yeah...it seems a little legalistic.
