First of all, ND use is optional and, if ND is used, RA must be used.
It means that, if RA is not used, ND can't be used.
Finding and maintaining the l2 address for a device on a subnet where RA is not used is a pretty common activity so I'm not sure how your would conclude that. 2461/4861/5942 certainly don't preclude that.
RFC6434 has contradictory statements: Neighbor Discovery SHOULD be supported. and Hosts MUST support IPv6 Stateless Address Autoconfiguration as defined in [RFC4862]. and a reasonable interpretation is SLAAC MUST be supported if ND is supported. Or, we shouldn't expect IPv6 specifications reasonable, which means reasonable operation is impossible. Masataka Ohta
