I don't see that that necessarily holds.  Isn't the relocation
information just a list of the points in the file where you need to
add the base address where loaded?  I don't see why you couldn't have
the MMU map the memory to start at 0 [as far as the program/processor
is concerned] and ignore the relocation information entirely.  Now,
you might have trouble getting something of the sort to cooperate with
the operating system, as Exec/AmigaDOS tend to assume everything is in
a single large address space, but I don't see that it necessarily
CAN'T be done.

Let it be a challenge.  :-)
