I think the "suitable RTL" is a reference to an earlier discussion about
this subject, where this (pointers) was also said, and that maintaining an
native RTL without pointers was not desirable.  (and just after that is in
the air the guaranteed destructors will start to that, and the systems will
divergate more and more )

IOW, only the compiler frontend is shared, nothing else.
