In principle this could be a good thing. But it depends on how the law is worded. I think something like "all manufacturers are obliged to provided the latest standard USB port at latest 2 years after the standard goes live" would be great for both the consumers and the state of the industry. I understand there are concerns that standard ports might slow down innovation, but the reality has been that without external push, there is no innovation at all. I mean, USB type A has been de-facto obsolete for years, but there are still new devices using it, simply because manufacturers are lazy, cheap and resultant to use good stuff, you name it.
