Re: [w3ctag/design-reviews] systemEntropy addition to PerformanceNavigationTiming (Issue #878)

We haven't had a chance to dive into this thoroughly yet, but first impressions:
* The term "entropy" has a number of other connotations and may not be the best term here. Possibly something like "systemLoad" might be more obvious to users.
* I don't have specific examples, but this leads to concern about possibly introducing additional information for side-channel attacks or user fingerprinting (see battery status API). I accept that this is past data, but it's strongly correlated with high resolution timers. Have crypto and privacy experts evaluated this aspect?
