The S-BFD documents - use cases, base and IP - have passed WGLC. However, there are authors who still haven't made their IPR attestations. Thus the S-BFD documents are in a holding pattern until we get these last attestations.
For draft-ietf-bfd-rfc5884-clarifications, we still haven't gotten IPR attestations from Kalyani Rajaraman and Sam Aldrin. More importantly, no one has actually stated that they believe this document is ready to progress. Santosh P K has also noted some items that must be addressed before the document can progres. -- Jeff
