  *   I don't have a strong opinion on whether to require a minimal encoding, but if we're not going to use QUIC's encoding as-is, then I would rather stick with the existing scheme, which has twice as large a range for the 1 byte encoding and is thus more compact for a range of common cases.

I was only thinking code re-use, but it’s only a couple of instructions so this is fine with me.  Leave it as-is.
