I wouldn't be at all surprised if Apple finds a way to continue monetization / licensing requirements for building approved accessories. For example, "you need to pay us for a crypto key that will allow the device to send audio over the USB-C port". At least if you're traveling and you forgot your charger, you'll (hopefully) be able to buy a standards-compliant USB-C charger for the same minimal cost you spend on a current micro-USB charger, and you'd be guaranteed that it would work properly.

I'm quite looking forward to the end of the "oh, sure, it's a 2A charger, but it doesn't deliver 2A to Android devices, only iOS devices" insanity. I'm similarly jazzed that we'll, someday soon, see multi-port charging devices akin to the Anker 5-port charger that can really charge everything: your laptop, your phone, your tablet, your flashlight, your watch, your assorted medical devices, etc.
