With a /28 you won't appear far in the current IPv4 routing tables either. Most sites filter prefixes longer than 24. How do you currently use such a /28 as PI? Or did you become a LIR and got that /20, just like is possible now with IPv6? As an exercise for the readers try to remember why there are filters on IPv4 /24 boundaries and the try to figure out why there are quite a number of people not wanting IPv6 PI to fill their IPv6 routing tables.
