Which is all completely besides the point? Reverse engineering and reimplementing the semantics of another vendor is obviously very much the opposite of "inventing random meaning", but rather "implementing a de-facto standard", and as such obviously helps interoperability. But that in no way justifies the first vendor inventing that de-facto standard in the first place, whithout wich there would be no need for anyone to reverse-engineer and reimplement it. If all deviations by browser implementors from the formal standard were reimplementations of deviations by other vendors for the sake of better interoperability ... there would not be any deviations at all.
