Unfortunately it may make things much more difficult for legitimate 
servers, too. :) Heck, we're still trying to get people like DreamHost 
to stop using _jabber._tcp SRV records 2+ years after they were 
deprecated. But at least they support SRV. Many DNS providers don't. 
However, I do agree it would be good to phase out the fallbacks, the 
question is when.
