This is a spec-compliant version of RTCPeerConnection.getStats returning a promise resolved with RTCStatsReport, a maplike containing RTCStats dictionaries. Stats are being implemented according to the spec in a continuous effort for coverage to become good enough that the old getStats method can be deprecated. The old getStats (taking a callback as argument) is very different from the spec and riddled with goog-prefixed things. It's anticipated to be out from behind the flag in 58.


While the feature has been behind a flag since M55, that version covered very few stats. The stats have continuously been added to getStats. A good number of stats are ready for M57, but not a complete coverage.
