Dumb question alert: why the 8 bit boundary? That makes sense for IPv4,
where reverse DNS delegation is cumbersome on non-octet boundaries, but
IPv6 reverse DNS can be delegated at the nibble boundary. Why not
assign /60, /52, etc.? A /60 would probably satisfy virtually all home
users (up to 16 subnets) for example.

I don't speak for anybody but myself - that's enough trouble.
