I think perhaps you are confusing "what must be supported by
implementations" (and ignoring the text describing the requirements) as
stated in 6434, with operational usage.
There is not much difference.
For example - SLAAC must be supported by the implementations, but an
environment isn't required to use it.
Still, if ND, which SHOULD be implemented, is not implemented,
SLAAC CAN NOT be implemented.
And, if RA is obsoleted, which is a point of discussion, there
is no reason to keep so bloated ND only for address resolution.
