I can answer that question, maybe, if IBM every embraces the "Open Software" and releases z/OS under a FOSS license. I expect this about the time of the heat death of this universe. Or maybe a bit later.
At a guess, I would say it might be because the IODF is never really "updated in place" like a PDSE. HCD "regenerates" an IODF by completely rewriting the entire thing. Which means that the internal structure is likely much simpler. Perhaps even more or least "sequential" in nature. Or perhaps, whereas the IODF people used the KISS principle, perhaps the PDSE architect used the (new?) <disrespecitvely/> KICK (Keep It [a] Complicated Kludge) principle.
