URL wildcards have been part of the product since eZ Publish. In eZ Publish, administrator users were able to define URL wildcards directly from the interface. This interface is missing from some customers migrating from eZ Publish.
URL wildcards provides a simple way to redirect frontend users or eventually fetch and display content under a specific URL. This is commonly use when you migrate and decide to reorganize the content architecture.
URL wildcards are already supported on PHP API. We want to expose it in Admin UI
