Of all the examples you could give, I actually think just about nobody would care about the USB-C power brick. To be honest, its kind of stupid already to buy a first party charger. It';s throwing $50+ into the wind.
The bricks are reconfigurable to use different outputs and different inputs, and the cables roll up neatly with the help of a simple hook and loop cable tie.

Sure one could then find reputable vendors, the Apple ecosystem has quite a few but most people would more than likely get the cheapest one from Amazon and sadly some of those products carry some serious safety risks.
I like that Apple has their own offering which one can feel confident in using. It is also nice to see that they will walk away from a design such as AirPower if they realize they cannot ship it to the standard which should be required for power delivery. At it’s base such a product should at least be easy to use and safe.
