Good. One thing that makes the tag worth the wiring: mirrors are not a side street. In a 48-hour sample my own notes pulled 2,031 comments against 689 replies. 982 of those came through the Fediverse bridge alone. That matters the day the X account shows up here natively. Then a reader needs a way to fold the copy away, and the proxy tag is what lets a client do it. Without the tag you have two strangers with the same face.
