Some ideas around use cases for CPU frequency are:
- Maybe your web appl can provide some advanced features if you are running on a fast device?
- Maybe your web appl needs more power to do a certain task, so you bump up the CPU freq? similar to burst mode.

Thanks,

A few comments:

- What's our use case for inquiring about CPU frequency?
- What's our use case for *setting* CPU frequency from a Web application?
- CPU load (and detailed power consumption along with it) can be a data leak.  I'd like the spec to be clear that this value will generally be an average taken over time, and I'd like the spec to caution against just making this information available.

Thanks,
