No we are not. GvR only uses this when his desired level of protection is
lower than others. If the other's desired level of protection is lower than
GvR's the all consenting adults goes down the drain.

Which doesn't support anything. Python has features that makes it in some
situations easier to cope with those consequences than when that feature
wouldn't be present. So there is nothing wrong in argueing for a feature
that would do the same.
