Shouldn't this requirement be separate from the underlying protocol requirements ?

Ignoring LL addresses, it seems that only self assigned addresses using deprecated methods (ie based on hardware address) actually *require* a 64 bit split. So on that basis, the standard defining how the protocols work should require implementations to support an arbitrary split.

Separate to that (in a separate section), make recommendations (as in "should") to support security and privacy.
