I agree with you. When such undefined behavior is
left in the spec, it's often because nobody found a
reasonable reason to implement or to impose a
particular behaviour to other implementors.

If, after some time, everybody seems to agree on
a common behavior about a specific edge case, it
would indeed be great to have the spec updated
to reflect this "de-facto" standards, as you say.
