No, I didn't say to deprecate that syntax, the syntax makes much sense.
I'm suggesting to return "USER <at> HOST" if both "USER <at> HOST" and "HOST/USER"
are present, because the former makes more sense.

When are you going to install this?  It's definitely an improvement over
the one in master, and doesn't have any problems to block it.
Installing it will also expose it to more users to the change, so this
will get even more testing.
