I don't think using the same prefix on multiple interfaces is necessarily a
goal The goal is to route an entire prefix to a host, such that different
hosts are guaranteed to have different prefixes.

That is true of *any* IP addressing mechanism. All existing mechanisms for
IP address assignment (SLAAC, manual configuration, DHCPv6, ...) can be
used on multiple interfaces simultaneously.
