my preference is also to not require that the prefixes be randomly assigned, in order to allow delegation of prefix assignment to multiple authorized parties. of course it's fine if those parties generate prefixes from within their delegated space in non-sequential order to further discourage attempts at aggregation and routing. but in practice I think the order of requests for PI blocks will be sufficiently random that aggregation would be infeasible anyway.
