Not really, and not architectures per se, but judging by some past experiences with enabling ASLR, I would expect that all kinds of weird applications may start to behave in all kinds of strange ways. Not that I have anything more than this doubt, however; but this sort of change without any ability to tune or revert it still looks unusual to me.
