And if that later date is the one following the assignment, so much the better.

Yeah, but the IETF set aside fc00::/7 for that purpose already and
only fd00::/8 is used for the so-called statistically unique
assignments. So we don't actually *have* to waste any new space to
make non-connected assignments from a distinct pool. At worst we'd
need a global policy to open fc00::/8 for assignment to the RIRs.
