In T89981 we split out the legacy feature (ResourceLoaderSkinModule) into multiple parts.
In T287410 we disabled its usage across all skins.
As part of the change we should also deprecate the content feature and content-thumbnails feature which currently act as aliases for other modules.
- legacy has been split up by no direct replacement
- content got superseded by content-media
- content-thumbnails got superseded by content-media
TODO
- skins that use the legacy option should send a deprecation warning to the JavaScript console. This will need to be sent inside ResourceLoaderSkinModule
- skins that use the legacy option should send a deprecation warning to the JavaScript console. This will need to be sent inside ResourceLoaderSkinModule
- Update docs/uidesign/design.html to include the appropriate styles once legacy is removed.
