Hi Fred,

Actually, SLAAC works equally well with off-link prefixes. There is no
inherent requirement in SLAAC that prefixes from which the addresses
are auto-configured must be on-link; the L and A bits in an RA's PIO
are completely orthogonal.

True, although 3GPP networks is an exception. There a /64 prefix
advertised to the UE via standard RA/PIO with SLAAC can be treated as
if it was a delegated prefix. RFC7278 depends on this.
