If SRV (with a fallback) is defined as part of the core spec, this
usage would use the fallback.
However in my opinion it could be good to document a recommended DNS
architecture for WS, that is judged optimal and the most
interoperable.
This could clearly be a separate RFC suggesting how clients and
server
can make use of DNS SRV records for HA and LB.
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.
