Re: [mediacapture-record] Fingerprint surface coming from 'isTypeSupported' - needs consideration?

> Those are informational for developers but they are not offered to the JS, i.e. a hardware accelerated version is only supported if and where there's a software fallback, and a positive response to isTypeSupported() is not enough to differentiate among them.

Is that intended to be a requirement? If so, that would definitely mitigate privacy concerns about easily detecting hardware properties, but I don't see a requirement in the spec that the list of types supported not be dependent on hardware encoding capability. Is it just Chrome's specific policy that new codecs/types are not supported in the UA unless software encoding is available for all platforms?
