I'm not sure I share this view. There are RFCs whose purpose is to
provide easy access to actual implementations, e.g., RFC 4634. They
are useful. I would prefer if more RFCs were accompanied with
relevant example code, because I find them helpful when implementing
the document (regardless of whether I use the code or not).
