GoKawiil's interpretation of the reporting above, not reported fact.
Interop has driven measurable gains in cross-browser consistency, with test-passing rates jumping from 29% to 97% during 2025 alone, easing frustration for developers who build for multiple browsers. Community input into focus areas gives web developers direct influence over which compatibility gaps browser vendors prioritize next.
