OTOH, it eliminates all worries about the SOA being misinterpreted, and really, 
this would be be remarkably small:

EG, I know I can code this up in prototype form in my (hackish) Python DNS 
library in about an hour, and the total codebase would be on the order of 600 
total LOC, including the DNS library.

So synthesizing an exact-match SOA should at least be considered, since it 
addresses the only interoperability concern I see with that of an overly-broad 
SOA record.
