The ECMAScript language syntax and semantics defined in this annex are required when the ECMAScript host is a web browser. The content of this annex is normative but optional if the ECMAScript host is not a web browser.
https://tc39.es/ecma262/#sec-additional-ecmascript-features-for-web-browsers

Features in Annex B are optional language features.
It's worthful if there is a rule to disallow those optional language features.
