@kolya @Gargron it could if people cared to implement it
i think one thing the fediverse could "learn" from AT is having DNS used purely for lookup rather than stopping there for identification. But even so, there are still other existing ways to do it. HTTP 301/302 redirects would allow translating DNS to DNS at least. And if you really wanted to do something similar to AT, you could just have a URN resolver for current locations...
