Not sure.  I assume it's a relict from ancient times when the main 
focus was "p2p with --secret" (where you could restart each end without
the other side having to notice).

On the server side, explicit-exit-notify is a bit more problematic today
(it currently interferes in strange ways with saved tokens on the client),
but on the client side I'm not sure I see drawbacks.

That said, maybe we should just make it pushable *and* de-FATAL it for
TCP mode (pushed or not).  So server operators can decide what they want.


(*That* said, reconnecting should still work :-) - a client could "go
away" without having time to send an explicit-exit - like, device crash,
power outage, ...)
