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
