Addons with build-time functionality, conversion may not be straightforward or not needed:

• @embroider/compat (not an addon)
• @embroider/core (not an addon)
• @embroider/webpack (not an addon)
• broccoli-asset-rev (unmaintained, and not part of the Embroider future)
• ember-auto-import
• ember-cli (not an addon)
• ember-cli-app-version
• ember-cli-babel
• ember-cli-dependency-checker
• ember-fetch
• ember-cli-htmlbars
• ember-cli-inject-live-reload
• ember-cli-sri (archived, and under Embroider, we should see if we can leverage something like https://www.npmjs.com/package/webpack-subresource-integrity)
• ember-cli-terser (not used/needed under Embroider)
• ember-template-lint
• loader.js (may be converted if we get rid of dynamism from index.js)
