I don't believe that this document should update 8446. As noted in S 1, we
didn't define these bindings because we didn't have complete analysis. This
document doesn't seem to either contain or reference such analysis and
until we have that, I think RFC 8446 shouldn't be retconned into endorsing
this construction.
