Their requirement is probably for their addresses to be globally unique.
Historical addressing plans being what they are, they probably have sparse assignments across all blocks. Re-numbering existing systems is a non-trivial exercise with high costs. There is no benefit to them to doing this, and we have known this exhaustion is coming for literally decades now.
Just because they're not in use on the Internet, doesn't mean they're not in use.

Stateful firewalls protect you. NAT does not.
