Sure, but if we can pin-point the sub-archs for which it is the problem then a flag to optionally request it is even easier to handle. You'd simply ignore the flag for anything but the P4 architecture.
I personally have no problem removing the whole thing because I have no such machine running anymore. But there are people out there who have.
