No; not register one but detect one under a well-known name and include it's properties (and allow them to override the default that way).

The problem is the `MetadataStore` is not iterable so we could only fetch properties we know about - unless we somehow add the metadata store itself available at runtime when accessing the properties (although we might want to do some caching to avoid round trips to Redis all the time).

Of course, this would also make the props available in SpEL Expressions.
