That is exactly what Apple will do: implement it by the spec. Then they can turn around to regulators and say they have done what they needed to do to be interoperable and, if compatibility problems arise, can point the finger right back at their competitors.
Why so cynical? Does Apple have previous experience doing such a thing? Typically everything they do they try to do well, and therefore I would expect them to make sure interoperability is good. The problem with Apple is that they only do what they want.
