Yes.

This might lead to fingerprinting, at least when using local
speech engines, so we need to be very careful with it.
It is a bit similar to getting keyboard locale, and that will be
possible only during key events (per DOM 3 Events), not any random
time to prevent fingerprinting.

And while an application will probably also need to specify a particular recognition resource based on the language it wants to recognize, this logic might be best left to the application.  These requirements are already covered (SRGS, and specifying what resource to use).  Are there other reasons for this requirement?
