I've written a few of them. But the argument here is about parsers that are not going to be changed. So, then you have a dilemma. I don't even feel strongly, but this syntax will break a lot of them. That's all it is. In what way does it "break" existing parsers? They simply return an error. Why is that a problem? As discussed at https://www.ietf.org/archive/id/draft-ietf-6man-rfc6874bis-05.html#section-4-1, this is completely compatible with stepwise deployment as and when needed. Yes, it becomes a feature request for existing parsers. And it will only get implemented when the need is irresistible. No different from any other feature request.
