Extracted from http://tools.ietf.org/wg/avt/minutes?item=minutes77.html , here is the text I was referring to: <http://tools.ietf.org/wg/avt/minutes?item=minutes77.html> Comment 2 --------- The proposed resolution is to remove the recommendation for a fallback solution. Robert Sparks accepted this proposal. ... Keith Drage summed up: the proposal to remove the recommendation while retaining documentation of the alternative and associated drawbacks is accepted. The author should send a text proposal to the list and we would go on from there.
