henbos has just created a new issue for https://github.com/w3c/webrtc-stats:

== scalabilityMode: Same as in getParameters() or not? ==
It was brought to my attention that if you ask for "L3T3_KEY" the encoder may still drop layers for adaptation reasons.
If I understand correctly, this means that getParameters() could say "L3T3_KEY" (just like you had previously set it), but getStats() might say "L2T3_KEY" or even "L1T3_KEY".

This surprised me, but at the same time, I think it makes sense that getStats() says what is currently happening, whether or not that is a subset of what was set in setParameters().

- Do we agree this makes sense?
- Does [the spec](https://w3c.github.io/webrtc-stats/#dom-rtcoutboundrtpstreamstats-scalabilitymode) need to be clarified?
