A question I have with this draft is the behaviour or expectations that may or
may not occur during failure modes, particularly when a "reset" or roll-over
happens on the server side. Consider the scenario when the server byte-offset is
effective reset, and thus it's "range" has shifted beyond the client's
expectations.

I don't see any reference in this draft that explicitly call out when 416
responses should be sent. Should these things be called out?

Regards
