Subject: [quicwg/base-drafts] Recovery draft unclear about when to stop sending an ACK for every packet when packets are missing (#1968)

Stuart Cheshire asked when QUIC knows to stop sending immediate ACKs.  I don't believe the recovery draft is sufficiently clear on what the optimal behavior is here.

The draft indicates when to stop reporting old ACK ranges, but not when to stop sending immediate ACKs, so you could easily end up sending immediate ACKs for a full RTT.
