Am I the only one who thinks QUIC looks a bit crazy with all its variable length fields in the frame, separate short & long header format, and rather high limits for certain things? 160 bit connection ids and 64 bit stream ids sound like something you'd benefit from if you're Google scale and building big-ass load balancers on custom hardware but I feel like there's going to be a lot of overhead for everyone else. (Consider that a TCP header with no options is as large as a single maximum size connection id in QUIC). At least the designers of IPv6 seemed to care more about efficiency, even if the protocol otherwise seems quite bloated and overengineered.
