(#ot56hla) @prologic@twtxt.net @movq@www.uninformativ.de Well, the original Twtxt Specification explicitly allows for the short form with just a URL and no nick: https://twtxt.readthedocs.io/en/latest/user/twtxtfile.html#format-specification

Mentions are embedded within the text in either @<source.nick source.url> or @<source.url> format […]

I’d just continue supporting it, even though I don’t see it all that often in the wild. I guess more common is the case where just a nick is given, which is illegal. But yarnd users seem to produce it every now and then.

What’s the motivation for deprecation?
