The updated text is fine with me as it at least accurately documents the fact that using that
feature is fraught with peril and reads more of a documentation of the behavior than
anything else.

On the plus side this spurred me into trying to put the thoughts I’ve had for a newer Wheel
format down into a PEP and I think it’s turning out well so far :]
