this is a huge move for a native code compiler. If FPC will follow, this

I don't see much work here. The code for handling interface references
exists, it only has to be applied to the new TObject type, too.
I'm not sure but afaik the current situation doesn't have any support for
breaking cycles. Heavier use will probably need that.
Cycles are one of the reasons for using Free or other explicit
finalizers, regardless of the GC model.
Mark-sweep collectors can remove also clusters with cyclic references,
but they can/should not call the destructors of these (any) objects,
because this could result in infinite recursion or other unwanted
effects. Clearing the references before calling the destructors is not a
solution, because it can prevent proper operation of the destructors.
