Vector will be split into 2 skins with key vector and vector-2022 (see Ibaddf94a5bfb5e21bbbaf1e0aa1b343a3f566d2d).
When this has occurred we will need to update all skinStyles keys across Wikimedia deployed code to reference the new keys:
Update the following so that any skin style entries duplicate vector with an identical vector-2022
Make sure to update skinStyles in ResourceModules
Do not change any existing skin styles (For example in Echo where vector has vector-2022 code) as it is not safe to do this until the migration has been completed.
Non-blockers (not desktop improvements wikis)
For these please provide a patch, but this can be broken out into a separate ticket if needed.
