It also says, "New gallery tools are coming soon for the VisualEditor", but this statement has been on the page since it was created six years ago, so I assume they don't have plans for it in the near future.

You can still use the contact link though to ask Fandom Staff about the future of New Images Galleries in terms of the VisualEditor and UCP.
