The only browser Apple is blocking it on is Safari: other browsers implement it just fine, and the standard passed over Apple's objections. The rationale was architectural, arguing that extending built-in components would lead either to brittle components that would break when new properties were added or causing the specification of builtin components to freeze forever to avoid such breakage. I'm not sure I buy the arguments 100%, but for sure it's not evil/incompetent board executives twirling their mustaches as they deliberately break the web: https://github.com/WICG/webcomponents/issues/509#issuecommen...

Standard practice in every decent frontend framework has been to create a component, that wraps the <button> without rendering its own dom node. This avoids the typical downsides of inheritance.

Can we not just do `:host { display: contents }` and use the same approach?
