Home routers would also have MAC addresses, but again, if we need a 32-bit quantity then shortened 48/64 bit identifiers may (theoretically) have collisions.
That being said, if the home routers have to discover their IPv6 prefix through a protocol and store it in flash, they could probably do so also for a router ID. Unless there was some chicken and egg problem that required the router ID for all this discovery to work...
