From the little I've seen / read regarding IPv6 I get the impression that people are starting to think of a IPv6 /48 in the same light as a IPv4 /24. As such a /56 will fall into the same hole as longer IPv4 prefix's in that no one wants to carry them. Same here. I'd not bother with a /56. I recommend using a /48 and nothing else. Same as for "special use v6 PI" - and the size has been chosen for a reason there.
There would need to be no mnt-lower or similar, to prevent people using /48 PI when they should really be becoming members of RIPE and getting a /48 PA. I'm still thinking about whether I feel this is a good idea. If v4-
v6 migration is going to work, then everyone who has some v4 PI is *probably* going to need some v6 PI. Perhaps sorting out the "does need" from the "should just get a slice of an upstream's PA" is going to be arduous, time-consuming, and possibly soul crushing, so I'm erring towards thinking that perhaps this is a good idea, it just needs some community refinement.
