Thanks for the issue. Even if the devices in the market today do not (commonly^) have multiple built-in microphones, it does not mean there wouldn't be such devices in the future. To future-proof the API, the [preferred facing mode][1] concept was specified to scale to microphones as well using the [media capture mechanism][2] abstraction.

(^Already today, one can add additional microphones via USB.)

This informative text in the said example:

>(without preferred facing mode defined, falls back to the implementation-specific default facing mode)

Maps back to this normative statement:

>The missing value default is the implementation-specific state.

I suggest no changes to the spec needed.
