While mailto: consumers have no compelling reason to split
an address into LHS and RHS this could get tricky with the
regular expression in the mailto.uri.arpa NAPTR

Maybe mailto-bis should do something with the NAPTR, if it
mentions the %40 magic as proposed by you:

RFC 2368 was based on 1738, and apparently 1738 allowed to
percent-encode "@" where it's not reserved by the scheme.

The problem of the percent-encoded comma might be related
to your question (opposite issue, why not use comma as is)
