Yes, though that would mean if we had to generate any register in there
we'd always have to generate at least as many entries as whatever number
it got assigned which depending on how much optionality ends up getting
used might be unfortunate.

Ack, though it's only 150 bytes or so at most, so just zeroing it all
(or as much as we know about) doesn't feel like a big cost.

It depends how determined we are to squeeze the most out of the
remaining space.

Indeed, I was more thinking about how it might scale as the number of
extensions grows rather than the current costs.
