I really hope this is based on a per-page user-given permission, same as access to audio/video capturing... Because if it isn't, any piece of adware code that loads onto the phone, would be able to run the tiny rotational-unbalance based mechanism within the phone for however long and in whatever fashion it sees fit. As if phone batteries didn't run down fast enough already...

If you click the small down-arrows on the Browser Compatibility chart, you can see the details about each browser that supports it. Most of them require a "user gesture", which is not as good as asking permission IMO but better than nothing. Firefox for Android used to ask permission, but for the last two years it just doesn't support this at all.
