The webrtc.org sdp corpus has a number of files with s= (no space!) which suggests that their sdp parser will accept this as valid input. Example here: https://cs.chromium.org/chromium/src/third_party/webrtc/test/fuzzers/corpora/sdp-corpus/10.sdp. RFC 4566 specifically says this value must not be empty, but if chrome is accepting it, we might want to as well just to avoid compatibility problems.
