Chances are most companies aren't going to make two separate production lines with and without a removable battery. The cost likely outweighs the profit i'd wager. Much like how we see apple finally begrudgingly moving to USB-C despite no NA law requiring them to do so.
I hope so too. But if somehow the cost to manufacture phones with removable batteries is higher then I doubt they'd switch the existing production line to removable battery. I hope I'm wrong, to be honest.
This is what happens in the US when California passes a big consumer friendly law. The companies just adapt to whatever California said because it's too expensive to have California versions and non-California versions. California's population is high and their economy is big. Double plus if NY is in on it.
