Hi Rich,

Cool, thanks.

You mean why we are using "DTLS-only" rather than "DTLS-OK"?

Or the fact that we don't have a "Comments/Notes" column?

If the former, it makes sense to invert the logic because RRC is
primarily a DTLS mechanism, therefore it'd always score true using
"DTLS-OK" semantic.

If the latter, we have an open PR to align with rfc8447bis [1].

cheers, t
