IPv4 Address Allocation policies for organisations not connecting to the Internet

There are a limited number or organisations that for legitimate reasons
require globally unique address space apart from rfc1918 private
address space, but may not connect to or announce these prefixes on the
Internet. Rfc 2050 referenced such situations as seen in the extract
below.
On a case by case basis, it may be appropriate for these few
organisations to become LIRs. Perhaps the IPv4 Address Allocation policy
should reference such circumstances as rfc 2050 did?

rfc 2050 extract section 3a
Assignment Framework
An assignment is the delegation of authority over a block of IP
addresses to an end enterprise. The end enterprise will use
addresses from an assignment internally only; it will not sub-
delegate those addresses. This section discusses some of the issues
involved in assignments and the framework behind the assignment of
addresses.
In order for the Internet to scale using existing technologies, use
of regional registry services should be limited to the assignment of
IP addresses for organizations meeting one or more of the following
conditions:
a) the organization has no intention of connecting to
the Internet-either now or in the future-but it still
requires a globally unique IP address. The organization
should consider using reserved addresses from RFC1918.
If it is determined this is not possible, they can be
issued unique (if not Internet routable) IP addresses.
