i'm not sure i see any "tearing hurry" to standardize *anything* in this
working group.

jari responded on this, yes there is some data.

these considerations apply to the SeND derived key for MN-AR as well. i know
you claim that the SeND license covers that, but i will only believe it when
we have the legal indication as none of us are lawyers.

yes, the operational implications of using CGA's are not clearly understood and
might affect deployment independently of any licensing issues.

i'm seeing this as a potential item, depending on whether a draft can be produced
in short order by the interested parties and deemed acceptable by the WG.
