I think one of the Friedens stated somewhere that it does not break compatability with software. I understand the old allocation methods still work (excuse my lack of technical knowledge).
Also with OS4's JIT engine, software known to have problems with the JIT are put on a black list which can be ammended. IIRC When a black listed program is run it is referred to the interpretive 68k emulator.
Therefore programmes that work now should still work when the final version arrives.
