A polyfill for Custom Elements builtin extends, enabling custom elements that extend native HTML elements.
Custom Elements Builtin is a polyfill that enables the creation of custom elements extending native HTML elements, a feature part of the Web Components specification. It solves the problem of browser inconsistency in supporting builtin extends, allowing developers to use this functionality across all browsers. This ensures custom elements can inherit the semantics and behavior of native elements like buttons or inputs.
Frontend developers building web components who need to extend native HTML elements for better accessibility and semantics, especially those targeting browsers with incomplete Custom Elements support.
Developers choose this polyfill for its focused, lightweight implementation that addresses a specific gap in browser support without the overhead of a full custom elements polyfill. It enables the use of modern web component features while maintaining cross-browser compatibility.

Specifically targets the builtin extends feature, keeping the implementation minimal and efficient, as stated in the project description for avoiding bloat.
Solves browser inconsistency by enabling builtin extends in older browsers, allowing developers to use modern web components features universally.
Facilitates building web components that extend native elements, ensuring better accessibility and semantics while maintaining backward compatibility.
The README explicitly marks this as deprecated and recommends @ungap/custom-elements instead, indicating it's no longer actively maintained.
Only polyfills builtin extends, not other custom elements features, which may require additional polyfills and increase setup complexity.
With no updates, it might not keep pace with evolving browser standards or fix potential bugs, risking long-term project stability.
