I propose to instead track this as "Add Resource Timing Level 2" which more accurately reflects the published specification. Adding every future modification as a partially-supported marking won't scale well I think. It also needlessly lowers the "browser support" percentage when looking for the original feature set of Resource Timing, which should remain easily available as well.

Level 2 has reached Working Draft. The editor's draft on GitHub is now for Level 3.

• Level 1 (Candidate Recommendation): https://www.w3.org/TR/resource-timing/
• Level 2 (Working Draft): https://www.w3.org/TR/resource-timing-2/
• Level 3 (Editor's Draft): https://w3c.github.io/resource-timing/

@Fyrd Could you tag as "Support data suggestion" ?
