JFC, In March, 1995, when RFC 1766 was published, the BCP track did not exist. The Standards Track was being used for things that were not protocols and did not fit well into the 3-stage process. Since BCPs are subject to the same consensus judging and scrutiny as standards-track documents, it's been common practice to obsolete old standards-track documents with BCPs when it's reasonable to think that the original document would have been a BCP if BCPs had existed at the time.
