This is to avoid a naming conflict with webrtc::RTCStatsReport that is surfaced if you try to include it in peerconnectioninterface.h. Background: The current stats is very much non-spec-compliant. A new stats collection API is underway that is meant to be spec-compliant. Some classes in Chromium and webrtc/sdk/objc have spec-compliant names but non-spec-compliant behavior. These are being renamed to "Legacy" so that new spec-compliant classes can be added with the correct names.
