Yes, it is a shame that the bitace thing references RFC4193 and then
does not use it. Lets Bcc: them and see if they act upon, you never know
if they fix things or not, there are good guys still left on these

I am wondering what you meaning with 'squat', note that what I reference
above is real full RFC4193 calculated ULA.

The optional registration thingy is just optional for those that don't
trust probability and want to have a little more security. Also lots of
folks like to claim something as their own and well storage bits are
cheap for that little amount of info and reassures a lot of folks.
