True, you have to ignore more than a decade of IPv4 protocol
development and resort to things like pre-VLSM networking.

Could you quote chapter and verse, please? RFC 4291 section 2.5.4
All Global Unicast addresses other than those that start with binary
000 have a 64-bit interface ID field (i.e., n + m = 64), formatted as
described in Section 2.5.1.
