Re: [w3ctag/design-reviews] Review Request: Priority Hints API (#241)

> this will decrease the risk of browser fingerprintability

Could you explain this point? I actually feel like this may increase browser fingerprintability right? Seems like it would increase the surface area for feature (and by extension, browser) detection.

RE website fingerprintability, I assume this is because to an observer, the network traffic to/from sites using Priority Hints might have a more distinguishable pattern, given the way/order in which resources are requested? Makes sense to me, but I think it is almost insignificant since each browser would likely respond to the hints in a slightly different way, so an observer would need to know the UA involved as well.

RE Firefox, I have no idea, but if so, it is an independent loading experiment that is not API-related, and therefore has no normative interplay with Priority Hints. I know Chrome, and I'm sure other browsers, are doing similar experiments to reduce network contention, but yeah, likely not related to the API, as they don't take hints from any exposed API source.
