@llimllib i think that issue is proposing cleaner display as well profile linking for bridgy users?
i’m not opposed, but suggest for people who do not actively bridgey, @<non-tld-dns-name> and @<identifier>@<non-tld-dns-name> are distinct, and we can take advantage of that to link.
(this does have “vive la difference” implications — it would militate towards preserving rather than converging mention formats, to maintain the existing distinction.)
