Could you elaborate on the anycast address generation problem?

Reason I'm asking is that even though the patch you linked to allow NM
to return to adding /64s in the case of SLAAC, there's still DHCPv6
IA_NA which are always /128, yet possibly in combination with arbitrary
prefix length onlink routes (if PIO exists in RA with A=0, L=1). I'm
thinking that perhaps this anycast address generation problem could be
present in that case too?
