Even Microsoft, a main proponent of this interface, does not conform to the definition.

Unnest in a LEFT JOIN LATERAL (clean and standard-conforming)

Sometimes we can’t implement a solution that’s fully spec-compliant, and in those cases using a polyfill might be the wrong answer. A polyfill would translate into telling the rest of the codebase that it’s okay to use the feature, that it’ll work just like in modern browsers, but it might not in edge cases.

This module is similar to JSX, but provided as a standards-compliant ES6 tagged template string function.
