This ADR restores a variation of the old Request for Comments documentation
that we previously used. The proposal differs from the original formulation,
and does not replace ADRs.
Per conversations earlier today, we'll consider all proposed implementation changes part of the ADR process rather than the RFC process (which will remain, for now, on the spec; this may get incorporated instead into the burgeoning "CIPS" process).
This change renames RFC 1 to ADR 66, leaving space for the not-yet-merged ADR 65.
