I think it's desirable (and you can go look in #bitcoin-dev logs for
me talking about it in the past)— but all of engineering is
tradeoffs... and the ones involved here don't make it a high priority
in my book, esp when people should be using Bitcoin over tor in any
case, which provides better privacy and also covers encrypt + auth.

In general I think authentication is more important than encryption,
since authentication is table stakes required for a number of
anti-partitioning-attack measures.  My past thinking on opportunistic
encryption is that once you're authenticating also encrypting would be
fairly little work, but it should be auth that drives that kind of
