I don't believe it has, no. Rather, we decided to trim this draft (as compared to our previous effort) to just the bare minimum using HTTP/2 as defined today in order to have something useful sooner.
 
We may expand to other suggestions going forward.

Reasonable recommendation, yes. Also in line with the goals of this draft of using existing technology. It is, btw, already included in RFC7925, along with other good recommendations.  But your comment points out that we left out a reference to RFC7925 (duh!). We'll fix that.

Will have to think this one over a bit. One of the recommendations is to use hardware-based crypto in order to save on code space, so any talk of new crypto suites as those you point out has to be evaluated in that light.

Thanks,
