Because wars have started over less than a bit field assignment. Setting unnecessary precedences is never a good idea, it is certainly a very bad idea if it is done without consensus of those affected. So do not do it. The establishment of regional registries will be driven by need, willingness and ability of groups of ISPs to achieve consensus. This depends on many factors is not predictable.

Quite frankly there is a lot of missing information before one can get that concrete. The most important piece missing is information on interdomain (exterior) routing schemes to be used. That's why I pointed out Mike O'Dell's 8+8 draft. Before routing becomes more clear any address allocation/assignment scheme needs to be very conservative in order not to preclude too many options in the high order bits. It also has to have the label "preliminary, provisional" because it may otherwise become useless. In the light of this and the fact tht we are not exactly overwhelmed by ISPs asking for IPv6 address space I doubt whether we need to discuss concrete schemes at this point. However we should keep this item on the agenda and have a discussion at the January RIPE meeting. We should also watch developments at the upcoming IETF. Daniel
