That some use it to mean something special is not in the RFC. Actually, a significant number of SMTP servers don't even implement the required parts of the related RFCs, let alone fancy things like plus handling.

it is not in the SMTP RFC because it is a purely local matter that does not affect email routing.

there are a number of servers that support it. wikipedia lists some if them:

Agreed, most of email servers and services are broken per RFC. I've blogged about this over and over again.
