Any just about any system worth writing an operating system for of the
scope of POSIX is going to have the hardware to do memory management.
Any system without MMU hardware probably lacks sufficient address space
or commercial interest to be worth spending hundreds of millions of
dollars developing software for.  And THAT is the real reason.  What
good is an operating system for machines that don't generate gobs of
revenue, or that no one wants to buy because they are overly restrictive?

As Dennis Ritchie says, if you want PL/1, you know where to look.
