However, it's not hard to imagine a site suggesting that people could enable Resource Timing, and have that timing information sent back to the site for analysis, much the same way many programs today allow users to opt-in to sending diagnostic information back to a server somewhere.

Hi Patrick,

I may have misunderstood the feature, but I don't think that is the intent. I believe that Resource Timing and Navigation Timing are meant to be on in a normal user configuration. Websites can then make use of these APIs to get real-world performance data in the field, from users' machines.

If the feature was meant to be opt-in and for developers only, then that would greatly reduce my concerns.

Perhaps someone more familiar with these APIs can explain the design.
