Pull request overview
Updates the repository’s ESLint configuration to enforce that all unused function parameters must be explicitly marked as unused by starting with _, helping identify unnecessary computed/propagated values (e.g., when cleaning up legacy GHES code paths).
Changes:
- Configure
@typescript-eslint/no-unused-varsto check all function parameters (args: "all"). - Keep the existing underscore-based opt-out via
argsIgnorePattern: "^_".

Do you think that this is needed as of #3497 since it seemed to be working as expected before that?

I think that's likely, though I haven't checked.

The default setting for this lint rule doesn't check function parameters, but in our codebase we are often cleaning up code paths for older versions of GHES, therefore it's desirable to check whether something is being passed that we could possibly avoid computing in the first place.
