Yes, so? Unless i'm misunderstanding what you are talking about, these are exposed to (untrusted) web pages through the web browser, the pages do not have a means of accessing it directly. So the browser can take measures of avoiding issues (e.g. decreasing the exposed timing resolution, like browsers now do). Then you can give your (trusted) native applications all the available resources without artificial constraints. (of course this assumes you see most native applications as trusted, but personally i see any alternative as too Orwellian to get behind)
