The biggest reason is that if that sw was ported to nitros9, you wouldn't 
have to reboot it at least weekly.  And there is not a thing that sw 
does that the coco/Nitros9 machine couldn't do, and do it on 10% of the 
power draw.

Amigados, up to at least 3.9, was still a flat memory system, with zero 
memory protection, so a wild pointer in CED would scramble a memory 
location it didn't own. A day, a week, sometimes a month might go by 
before that corrupted memory was accessed again, and then you have 
another guru meditation & reboot.

The only exception to that rule/problem that I am aware of is the PP&S  
68040 card, with 64 mags of dram on it, that I had and that Richard 
Crislip now owns.  It has a memory manager chip that was  almost 
properly used by the 68040.library that came with the card.  
Unfortunately, that library was also considerably slower that the Commie 
version, and BOTH still had some wild pointer writes that could crash 
another program also multitasking with the system.  How many of those 
Thomas Richter at math.tu found and fixed I don't know.  The bigger 
problem was in getting those fixes into the hands of the end user.
