Description

via https://github.com/mdn/browser-compat-data/issues/27427#issuecomment-3184424942

Some browsers are not represented in some feature entries, while others are presumptively version_added: false (e.g., browsers without any webextensions don't get a key in support instead of version_added: false).

We ought to scope certain browsers to certain trees (e.g., don't allow Node in the html or css trees) and use allowlists in trees that may have a mix of relevant and irrelevant browser scopes (e.g., for Node, allowlist—with with wildcards—certain api subtrees).

Research direction

Read the linked browser-compat-data issue and comment first, then locate the existing validation or lint entry point for support trees. Done means the relevant browser scopes are constrained or allowlisted consistently, and the lint rules enforce the required false values without rejecting valid entries.
