Describe the general question related to the W3C Process or its implementation

The process is rather clear how a registry is managed once it reaches the W3C Registry status. However, it is not clear what happens until then. In the Web of Things WG, we have started a discussion about this and reached a preliminary consensus, but we are not sure about it. See the linked issue at w3c/wot-binding-registry#22

What happens if someone wants to submit a registry entry before the registry is finalized? Can we collect entries before becoming a "W3C Registry"? What happens if we change the registry definition after there are living entries in the registry?

All groups have entries before becoming a W3C Registry, but given that there are still no W3C Registries (see https://www.w3.org/TR/?filter-tr-name=&status%5B%5D=ry), I am not sure what will happen then.
