I agree with Nick. If you want to do some research on the history of some prefix.. where it came from, what geo-location it had .. or who the previous owner was or how large the prefix originally was.. It helps to be able to pull that data from the DB. Currently, parent blocks are simply deleted or removed .. and with them, the history .. I would like to see parent prefixes to be ‘de-activated’ .. or something .. so that you can still query them with some special flags.

The current implementation blocks version data if the number resource has ever been de-registered in the past. I would be in favour of seeing the full history. Nick
