We already have a sentence that states when a packet number encoding of certain length can be used. Quoting [section 17.1](https://quicwg.org/base-drafts/draft-ietf-quic-transport.html#rfc.section.17.1): _The sender MUST use a packet number size able to represent more than twice as large a range than the difference between the largest acknowledged packet and packet number being sent._

Therefore, I think that the only debate is if we need the 7-bit encoding. My preference goes to retaining it, because it would be useful in some cases, and because I do not think we have new information to reopen the issue.
