Not yet. I want to use the OT's feedback to assess the solution's viability.
Exposes the (experimental) soft navigation heuristics to web developers, using both PerformanceObserver and the performance timeline.

WebView application risks
Does this intent deprecate or change behavior of existing APIs, such that it has potentially high risk for Android WebView-based applications?
Goals for experimentation
I'm interested in gaining insights on the quality of the heuristic and how it compares to current heuristics employed by RUM providers or driven by framework- or app-specific knowledge.
I'm also interested in knowing if developers find the correlation of various performance entries to their soft navigation ergonomic, and whether the emitted FP/FCP/LCP entries work well for them to evaluate the performance of their soft navigations.
Reason this experiment is being extended
Ongoing technical constraints
Will this feature be supported on all six Blink platforms (Windows, Mac, Linux, Chrome OS, Android, and Android WebView)?NoYes!
