Ya ya yawm TAG!

I'm requesting a TAG review of Performance Timeline.

This is actually a request to confirm or amend previous review, as requested in the CR transition https://github.com/w3c/transitions/issues/339#issuecomment-850639142

This specification was originally developed in levels, Level 1 in REC in 2013, Level 2 has had a wide review in 2016 before entering CR https://www.w3.org/TR/2016/CR-performance-timeline-2-20161208/ There is no fundamental change to the goals of the spec. The processing model is more detailed and data structure updated. We plan to drop levels and use a living standard development model (from process2020).

• Explainer¹ (minimally containing user needs and example code): giving the history of this spec, its scope is hopefully well-understood at this point. From the Director's comment in the CR transition request, it seems that only recent changes would eventually need a review.
• Specification URL: https://w3c.github.io/performance-timeline/
• Tests: [wpt folder(s), if available] https://wpt.fyi/results/performance-timeline/
• Security and Privacy self-review²: https://w3c.github.io/perf-security-privacy/#privacy-and-security-considerations
• GitHub repo (if you prefer feedback filed there): https://github.com/w3c/performance-timeline/issues
• Primary contacts (and their relationship to the specification): @yoavweiss, @caribouW3
• Organization(s)/project(s) driving the specification: WebPerf WG

We'd prefer the TAG provide feedback as (please delete all but the desired option):
