Email address can contain @ in the username part - the identifier is the
last @ in the address. But Emails don't have resources. We would have to
decide which is more valuable to have in the node part allowed - one of
them can not be allowed.

Just wanted to point out it is theoretically possible to have @ in the
node too.

Anything is possible, unless it's not.
