This is the heart of the problem. Everybody think like that and this is precisely the problem.
I could agree that .doc has been a de facto standard (and now you understand why MS has never really taken action to prevent piracy of their products: let the world get accustomed to them so that they can't live without them, there will always be a part of them obliged to buy the product).
But .docx is not a de facto standard at all, it's just a new file format that is not even supported by MS in its ISO version.
Imperial system is also a de facto / historic standard in many parts of the world and I recall the crash of a satellite because somewhere in the software it had not been converted in the international system (metric) used by the other parts of the soft. Same here: if users want interoperability, then use formats designed for that.
But we have to revert 20 years of habits...
