so, to the question i think fred meant to ask, TCP fallback is an expectation we can have, and it's full-resolver behaviour that we can rely on, even if some full resolvers don't support TCP fallback and rely on UDP fragmentation.
In my mind, it is fine to say that RSSAC (or some other RSS-y body) expects resolvers to be able to do TCP fallback. That is, some or all of the RSS will act based on that expectation being fulfilled. --Paul Hoffman
