If RFC 1918 address space is good enough in IPv4 I find it hard to understand why RFC 4193 space would not be good enough in IPv6. RFC 4193 is far, far less likely to suffer from any address clash problems and is very unlikely to ever be routed across the Internet.
Unless I misunderstood Owen's opening paragraphs, it sounded
to me as though he's putting this grand unified address allocation
idea forth in order to incorporate all v6 allocations, including the
ULA addresses mentioned in RFC4193.

While such cases might exist, people with special needs generally understand that their needs are special and understand what that means. If it means paying a registration fee of some kind then presumably that would be acceptable to most people if it gave them the guarantee they were after.
If this is *not* subsuming RFC4193, but would be a parallel
track as an alternative to RFC4193 addresses, then yes, I
Owen, can you clarify whether you intended this to be an
umbrella which also applied to unique local addresses
as defined in RFC 4193, or as a a parallel source of
addresses separate from RFC4193?
