More similar, perhaps, to an Intranet web site where the full domain name isn't specified, nor available to the rest of the world.  In my experience such links are usually for the contact of an intranet web site or group or something and they never "go public."  (If they might go public, the full form would be much better.)

It seems common, in enterprises at least, to have such internal/intranet resources that aren't fully specified.  I wonder if perhaps the standard should allow that mailto: without an @ MAY be used for Intranet use only?  Of course I could argue that if it's for Intranet use only, then it doesn't need to be in an IETF standard :)  Since many tools work in both Internet and Intranet environments, it might be good to allow the common practice.

By diverging from RFC 5321, you may be introducing some
ambiguity.  Today's Intranet environment might be moved to the
Internet tomorrow.  Your mailto:local-part will be qualified and you
cannot tell where the message may end up.  Standardizing (not IETF)
is generally less work.  If you do not take out the "@", you still
have some semblance of an email address.  If you keep "At-domain",
you make it easier for the IETF. :-)

I adopted an approach similar to yours many years ago in an
environment that was not an Intranet.  I would not adopt the same
approach now as the boundary between private and public is blurry.
