So, you agree that it's possible emulate POSIX in a non POSIX system, this is a
good point =)

If we create a layer, they will run natively on this new design. And, as I
said, many programs could be adapted to use the best resources of this new
design, others will need to run on a special layer/emulator as long as they are
not adapted to run in the best way of this new design.
This is not silly/weird/strange/etc. Many systems do that when they do big
changes on their design, why we cannot do that?
