For the uninitiated, can you please expand on what the @wordpress/scripts package is and why it should be switched to?

[ntwb]

This repo was still using the deprecated ESLint config, the replacement is @wordpress/eslint-plugin so the vast majority of code in this PR is updated to adhere to the latest WordPress JS Coding Standards, which is what Gutenberg uses, as will WordPress Core.

The @wordpress/scripts package also includes styleint, Jest, npm-package-json-lint configs as dependencies which ship with a default configuration, this default configuration which is inherited allows for zero configuration here in this repo. As such this repo removes any and all ESLint, stylelint, Jest, and npm-package-json-lint configurations greatly simplifying the configuration of the build tools in the repo by not requiring any configuration whatsoever.

** There is one minor config tweak added in .stylelintignore here so that the stylelint Jest tests that are part of this repo run the stylelint tests using stylelint-config-wordpress against the valid CSS & SCSS test fixtures but ignore the invalid test fixtures.

[GaryJones]

Is it foreseeable that eventually there would be a @wordpress/stylelint or similar which would make this stylelint-config-wordpress redundant?

[ntwb]

Yes @GaryJones, this repo will be deprecated and moved to the Gutenberg packages and become @wordpress/stylelint-config
