The problem here is that you can't change the standard, even you know that it states a silly thing or doesn't state an important one. You're writing a standard at the time when you know the least about how and why the thing you spec would be used. You can't get it right (you still can do "mostly right"), but you desperately need to sneak some fixes. So yes, you should have hot-fixes to standards just for those cases. One would state that the response of 302 for POST/PUT/DELETE should unconditionally trigger GET. And it should be in the spec years ago. And no, you can't just "increment version number". Realistically you can't, pretending you can is silly too. There is the same problem with laws: you first pass them, then you discover some flaws but no easy way to patch.
