Except for SLAAC that requires a /64 due to it using EUI-48 to make up the address, which "applications" are these, as those applications are broken by design.

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. -- ++ytti
