A philosophical argument that websites don't need to function identically across all platforms, drawing a parallel to the earlier debate about pixel-perfect visual consistency. The post argues that input-specific features (keyboard shortcuts, touch gestures, hover states) are a natural and desirable form of progressive enhancement. It examines how this unresolved belief is actively blocking web platform feature development, citing Interest Invokers, Overscroll Actions, and the Document Picture-in-Picture API as concrete examples where cross-platform uniformity expectations are creating unnecessary friction.
