I don't see the advantage of only putting ufrag and not pwd, to be
honest: if SDP parsing is the only way to get ufrag/pwd in specific
implementations, then once you've got one you may as well get the other
too. Same for the m-line: once you've done parsing, even in the case of
bundling it's easy to figure out what media the first m-line contains.
