For Amithlon, there is a nifty little tool called PuhDerBear, as well as a couple other such as NewBear

Which redirect all audio that depends upon the Paula chip, to AHI instead, thus allowing Amithlon access to more classic apps than any other next gen Amiga OS alternative.

So I am wondering, what is to prevent someone from writing a tool like PuhDerBear for MorphOS?

Likewise, what is to prevent someone with the coding skills to write something like The Maestrix for MorphOS?

MorphOS was created to keep the Amiga legacy alive when all looked bleak for Amiga OS/Workbench. So it has always boggled my mind that no effort (and I don't say this to sound jaded) has been put into stretching backwards compatibility as much as possible. If we had programs such as these, all new doors would be opened on our beloved MorphOS machines.
