I'm not following something here. Could you elaborate? Caching doesn't
mess things up in the DNS, unless one is using kludgery that is known
to be inconsistent with the basic DNS architecture.
Exactly .. the inbound TE part would be exactly such kludgery.. which
is why it shouldn't be used :-)
unless remote resolvers explicitly query for the SRV records, and they
use that information to order the list of addresses returned to the
app, in which case this works and does not require upgrading the app to
query for SRV records. In this case, there is no kludgery AFAICT and it
seems to work fine and be easier to deploy. imho this may be useful if
we go to the path of using the DNS to express preferences about
locators for incoming communications
