Is "anything ending with '@'" (in your version) the same as
"any non-'@' ending with the first '@'" (in JimC's version)?
For clarity I'd prefer the first version, but maybe we are
not yet ready:

As soon as you are behind the <userinfo> in an <authority>
it is not more necessary to percent-encode '@'. I'm too lazy
to check it, but I guess that '@' is an ordinary <pchar>, and
also allowed in query parts and fragments.
After all mailto: and news: URLs use '@' for their purposes
outside of <userinfo>.
Therefore we might need something in the direction of...
!^ftp://([^@/?#]*@)?([^:/?#]*).*$!\\2!i
...matching '@' only before any path or query or fragment.
[^@/?#]* should match the colon in a user:pass <userinfo>.
