Purpose/Function of Reference Tags

Would be nice if we could use this “reference tag” feature to share UDT definitions between providers (e.g. something like what is asked for in this post: [Feature] share or sync UDT data type between 2 realtime tag provider).
Are there any plans to create a “global” tag provider – e.g. where UDT defs can be defined/automatically inherited by other tag providers on the gateway?
