If the standard is not willing to declare existing implementations to be broken then it has to allow the existing stupid way, but it doesn't have to mandate the stupid way. The standard could say that it's unspecified whether it works the smart way or the stupid way. The standard could also deprecate the stupid way and say that a future revision if the standard will require the smart way.

I'm kind of hoping for something more than "no urge" --- I'd prefer an explicit statement that NetBSD is going to ignore the standard in this area.

Me too.
