AmigaOSes (AOS,MOS,AROS) should be hardware independent*, if we want to survive: The hardware is obsolate after a few time, but the software can be upgrated relatively with ease.
The point that Linux is h/w independent isn't valid: the user base has x86 on its majority, and that is the driving force (cheap hardware).
We had to stuck with old hardware (over 10 years) due to custom h/w and h/w-dependant OS. I don't believe that you planing to have the today's solution (A1 or Peg) for the next 10 years (just to write off the expenses!!!).
With a compatibility through the 3 solutions, the s/w development would be easy to port on a large scale with no time delays.
*Before someone says "yes, but the above OSes are designed independently from the platform", noone can run them if he hasn't an A1, a Pegasos, or a PC, respectively...
