Currently, the new Vector skin is marked as skippable inside Vector's skin.json. This means it is not configurable, meaning we can't make it visible on a single wiki for testing.
To support roll out of the feature a couple of technical changes are required noted in the TODO.
# TODO
[] We'll update mediawiki-config SkipSkins to hide the new vector-2022 skin
[] We'll remove the skippable flag inside Vector's skin.json
# Sign off steps
[] Prepare a QA task for making sure we are ready to proceed with the skin migration
[] Prepare task for managing the deployment (enabling the new Vector on a single wiki for production testing, then enabling everywhere)
```$wgSkipSkins = [ 'vector-2022' ]; $wgVectorSkinMigrationMode = false; $wgDefaultSkin = 'vector';``` =>
```$wgSkipSkins = []; $wgVectorSkinMigrationMode = true;
$wgDefaultSkin = 'vector-2022';
