By the time it's a problem it'll not be fixable.
I've been a supporter of classful allocation of v6 such as Bill mentioned
there's enough space for it but people don't want to do classful again.
If there isn't standard filtering of defined prefix/lengths by major
carriers then we're just waiting for the problem to arrive. I don't
think we'd get enough people to agree on this to avoid it.
