Why? Did you also care about that with micro-B on Android? Or when using different wattage lightning chargers from Apple?

It's up to you to read the wattage on them an decide which one you want to use. Mobile tech has gotten more powerful and so have the chargers.

It's your responsibility to keep track of the chargers in your household, but the great part is, even if you don't and mix them up, they'll both charge your phone either way, just ar different speeds, and most likely any other low power type-C gadget in your household like your earbuds. You can't expect us to go back to having different plugs for different wattages just because you can't keep track of the different chargers you own. Devices and chargers are smart and they'll negociate the quickest and safest charging wattage regardless.

Since you're being obviously obtuse just to be snarky, I'll stop answering your questions as i think i provided enough arguments so far.
