The point here is that if there is a way to get it without a performance cost (I can't imagine there would be, it's got to add a check for whether you're overriding a method at a minimum, but you may be able to come up with something) then you can do that within the language as it stands. It may need a specialised metaclass, but that's not a problem. At least, if it *is* an issue to you, you can argue for having it be the behaviour of the default metaclass once you've demonstrated that it works and doesn't hurt performance. And if there is a performance hit, then having the behaviour as opt-in based on a custom metaclass means that people can choose if they want to pay that cost.
