Hi, thanks for working on this draft! While I was not aware of the "BBF Technical Report - Subscriber Sessions Issue 1" (TR-146) from 2013 already mentioning the idea of using BFD Echo packets without an associated control session before reading this draft, I realized this possibility when first reading the BFD RFCs in 2017. In 2019, I mentioned this idea on the "Linux Advanced Routing & Traffic Control" (LARTC) mailing list <https://lartc.org/#mailinglist>, where it was not widely known. The "Unaffiliated Bidirectional Forwarding Detection (BFD) Echo" draft provides a full specification for how this idea can be realized, including comprehensive security considerations. This is a significant improvement over what TR-146 provides or the discussion on the LARTC mailing list. Publishing this draft as a Standards Track RFC incentivizes the creation of conforming implementations, providing a useful function with clearly described behavior to rely on.
