Validator registration idea

So as I see it validators are businesses.

Every business needs to be registered. This registration is needed because delegators need to know who they are delegating too, how to contact them and if those validators are capable running a node.

With a registration comes a unique id. This id will give you permission to run one validator and a backup validator.

1 unique id is 1 business. Multiple businesses can own on one validator and split the rewards, costs etc…

The unique ID will also give you a fixed amount of slots. And a fixed max delegation.

This is just a brainstorm for now…

I guess that goes agains the decentralization idea. Who gives that id? what do you need to register? Who decides what?

I am sorry but i cannot see any benefit added to this.
