Alia: The SIDR WG wanted to reference rsync, but there was no stable reference that described the protocol, only the code. A document was written to specify the rsync URL, and they is the only thing that is normatively referenced. A reference to the protocol would be better, and I hope this BCP would allow that to happen in the future. Section 2 is written as a list of questions. In some cases it is unclear to me which answer to the question makes an acceptable normative reference. A list of requirements would be more clear.
