I concur with Dick here. Unless we strip the “core” first, we would be either unable to finish the work because we would endlessly bicker about what to put and what to leave out; or we would end up with even worse superset of what we already have.

Stripping down the existing RFCs one-by-one, then just documenting what we already have without changing the content and producing the one “core” document obsoleting 1034,1035 is reasonable approach that could lead to an actionable work plan.
