Strictly speaking SLAAC standard does not care about network size, you could
specify standard using SLAAC for arbitrary media with arbitrary network size.
In Ethernet EUI-64 is used, but that is not hard technical limitation, infact
Cisco IOS happily will accept any prefix size in Ethernet and SLAAC will work
fine.
SLAAC never makes any guarantees of uniqueness which implies network can be
arbitrarily small, as some other method (DAD) is needed for uniqueness
guarantees.
