A week-ish later - it's working! Rebuilt my React+Redux dispatch+render perf POC on top of Replay's current infra. Currently extracting dispatch+render timings and selector calls . Just raw data atm, but now I can build meaningful visualizations / perf analysis with this! time travel's awesome!

btw, worth noting: this _ought_ to give real perf info _from production apps_! React DevTools is normally dev-only. Helpful for relative ("Comp A is 3x as slow as B"), bad for absolute. Replay can inspect _prod React_ (with sourcemaps). So I can get timings for recordings of prod apps! :)
