"it is trivial to strip suffixes off of aliased email addresses ..."
This actually is not a bad point to make ... it would, in fact, be simple to strip +aliases but ... economically I don't think it makes any sense.
You'd have to have a high level decision maker dictating an engineering fix in order to increase email authenticity by ... .01% ?
... and that assumes that the "engineers" down the chain understand how '+' works in email to begin with and have somehow communicated that back up to management.
