I think it's mostly humor. Bugsmithing and interoperability impedance of this form was almost Microsoft's raison d'etre in the 90's. Stuff that was simple and obvious everywhere else just didn't work on windows, even though the fix would be 100% trivial and probably result in better standards compliance. And MS liked it that way.

So sure, this is good. It doesn't exactly undo all those decades of grief. So we're laughing grimly at the "progress".
