Hi Dijk,

you actually might have a point there. While we have discussed it during
several IETF meetings we might have overlooked that explanation on the
draft itself. We hve added several clarifications and I am wondering if

@cabo you would be OK with adding that short motivation that Dijk is
suggesting. It could for example fit nicely on section 2.1. 

Ciao!

Somewhere it should state e.g. "re-purposing the version number is preferred to adding an additional feature-bitmask field in a version-11 format, because shorter to encode in average use cases".
