Since all of these are possible today, won't all application or
transport protocols need to deal with the possibility of these
Sure, and the concern isn't that apps and transports can't deal with
these events when they happen. However, dealing with these events
usually has some negative performance impact.
The question is if any of the proposed layer-3 extensions increase the
probability of these events happening to a degree where user-perceived
performance is significantly impacted.
And the answer may well be "no, they don't", but I'd be good to back
that statement up with data.
