Nice to have guidance (was: Re: Reprioritization - implementation intent)

Hi Eric,

Just responding to your side note

Thanks for your feedback. I think this is orthogonal to the
reprioritization issue so I've created
https://github.com/httpwg/http-extensions/issues/1232 to capture your
comments. I think this might have some cross over with
https://github.com/httpwg/http-extensions/issues/1216 so if you coud take
at look at those and add anything more to them it would be appreciated.

Cheers
Lucas
