If SRV (with a fallback) is defined as part of the core spec, this  
usage would use the fallback.

Okay, a thought experiment for you.

Let's assume we go ahead with dumb A/AAAA lookups.

How will it be possible for a server to later inform browser it  
wishes to use SRV lookups?

If you have an answer for this, we can make it optional, and moreover  
we can deploy SRV for HTTP as well.
