Yes, we should scope this discussion to RW and DPR. This is consistent with
Blink implementation [1], and to keep this thread focused I'll skip the
comments on MD/RQ/etc. That said, happy to discuss those in a separate
thread :)

Uncompressed bytes on the wire add up quickly and short names are
consistent with general policy of keeping those at a minimum. I don't
believe this is counter to HTTP WG goals or guidance. That said, I'm not
opposed to renaming them if there is a strong preference one way or another.

Big +1 to that. This is all great feedback, thanks Maciej.
