Hm interesting. I am not so sure about that, but it is certainly not a
much used feature (yet). Which is probably related to the fact, that it
is not very usable as it was. :) OTOH there was a huge interest in that
features in the last months from Intel users due to the ME limitations
(which was also my main motivation to work on it). In any case I don't
think that the migration would be very tedious. Carldani brought up the
compatibility issue back when david wanted to change the address base:
