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

Currently, the first example in the specification demonstrates how to enumerate the list of supported codec/container combinations in the user's browser:
https://w3c.github.io/mediacapture-record/#example1

I don't think you want to recommend doing this kind of enumeration, as it's a particular example of what a site would do in order to fingerprint a user's device rather than detect a capability in order to provide functionality. Some browsers might want to limit the number of successive `isTypeSupported` calls to limit disclosure.
