Put another way: we lived without DEBUG_RODATA for fifteen years, why should we now start adding complexity to work around code that doesn't accept the (fairly small) debugging it gives? Has anybody actually found a bug using it? As far as I know, the biggest reason to use DEBUG_RODATA is (a) Hey, it's a cheap way to check one thing (b) An added layer of security (which it's not that great for, but it might make sense to make it more of a real security feature). and neither of them really seems to say "let's add more code to other pieces of the kernel to work around it" to me.
