Don't think so, "domain does not exist" is general enough. Some
mechanism to discover a say jabber server might use SRV and NAPTR
magic, but if the domain doesn't exist there is also no magic to
worry about.
And ADSP is for RFC 2822 messages, not IM, SIP, or what you have.
If there's a problem (apart from step 3) I think the draft needs
to mention that domain literals should get ADSP result "unknown".
