A regulation requiring companies to "let consumers decide inputs/outputs" would be much more burdensome than merely standardizing one specific connector per ~decade. With the compactness of modern devices, they'd basically have to spin a new board for every connector type a consumer might what. But you're right - it would be kind of neat if I could have Google make me a new Pixel 8 with the bespoke data connector from my old SPH-A580, so I'd finally once again have a use for that cable that's just sitting around in a box. This is what you meant, right?
