There are places where the shortest possible encoding is an important property to have, such as frame types. There are also places where it is not important, such as long header's payload length.

Losing the flexibility afforded by allowing fixed-size varints is one way to fix the clumsy language. The other way is to fix the clumsy language.

I suggest we add a definition for the shortest possible varint encoding to [Section 16](https://tools.ietf.org/html/draft-ietf-quic-transport-17#section-16)&mdash;we can call it _minimal_ varint encoding or something of the sort&mdash;and reference it in other parts of the documents as appropriate.
