Ahh, this gets into whether it is necessary or sufficient information to identify a QUIC version and whether we need to say anything more.  "can" might be read to imply that it is sufficient, though "can" doesn't imply necessity.  But "can" also means that it is possible for endpoints to use the field.  That is the meaning I intended and I think that's OK.
