The Brussels EU big-wigs very likely don't use cordless power tools personally (unlike mobile phone chargers), so it will probably take a few more years until it reaches their radars. And then it's 50/50 if they'll do something smart or stupid about it. They will do something, though.
Edit: There's also the financial interests of german companies like Festool, Bosch, Metabo, Stihl, Einhell. Imagine if they were forced to use a common battery format so that anyone could build a battery for their tools?
They don't want to deal with up to three companies being liable if a battery explodes or catches fire. It's not easy to legislate. EV charging is already challenging enough.
