Re: [quicwg/base-drafts] Should QPACK use the new layout? (#3999)

[Mike Bishop <[e-mail]>]

Personally, the "nonsense" of a byte grid doesn't bother me as much with H/QPACK as with others, and I think I've figured out why:

- Things are presented one byte at a time instead of four bytes at a time.
- Prefixed integers will take up the indicated portion of a byte if they fit, but might spill over to additional bytes which come before the next byte shown.
- QUIC fields were presented four bytes at a time, containing varints which messed with four-byte alignment, so the byte grid never made sense.

I kind of wish there were a better way of indicating visually where these possible extra bytes would fall (=== vs. ---?) but the + in the field length is a strong clue.  If folks think the old format is better to stay in sync with HPACK, that's fine -- I just wanted to have the PR and make sure it was a decision instead of inertia.
