USB Type-C is not all over the place, it's a pretty normal connector standard, that was updated a few times.
What may be confusing to is that there are also two other relevant standards:
Both of these standards require the USB Type-C connector for some of their features. Sometimes in a specific revision, for example at least USB Type-C Rev 2.1 is required for the Extendend Power Range introduced in USB Power Delivery 3.1 for charging at more than 100W.
Furthermore USB 3.1 has absorbed USB 3.0 and USB 3.2 has absorbed USB 3.1. Each time they renamed the old connection speeds. For example a USB 3.2 Gen 1×1 connection used to be called a USB 3.1 Gen 1 connection and before USB 3.1 came out it was called a USB 3.0 connection.
Finally USB Type-C has so called alternate modes, where the lanes for SuperSpeed USB can instead be assigned to carry other protocols, like DisplayPort.
Since very few features are actually required to be supported, and marketing managers are apparently allergic to precision, it's hard to find out what feature is supported on which interface for any given device.
I think what confuses people is precisely the fact that we finally have one universal connector, because previously each connector basically only had one set of standards.
USB-C is a victim of its own success
It is all over the place. The connector allows for all of those things and doesn’t guarantee any of them. Along with that cables don’t even have a guarantee of being bidirectional, a problem with the usb c spec, not with the USB standards.
Also you kind of proved the point. USB C is confusing because it pretends to be universal (see literally the hundreds of comments in this thread) even though it most definitely isn’t.
In reality USB Type-C is only a connector, not all the features people associate with it. Of course it's going to be confusing if you insist on mushing the concepts up in your head even after an explanation. Just accept that there are at least four different things, Type-C, USB 3.2, Alternate Modes and USB PD, and start thinking in those categories.
Dude. The connector allows for different sets of pins. This is not mushing up different concepts. I’ve actually soldered usb c connectors. I’ve even designed PCBs that needed to support PD. Have you read the USB spec? I have. It’s clear you don’t actually understand how complicated the connector itself is.
