As long as it just charges as fast as the standard usb-c norm, it’s ok.

Charging is essential and had to be standardized. Fast charging is a bonus.

USB-C doesn't have a standard charging norm. It's just a connector.

https://www.usb.org/usb-charger-pd says "The USB Power Delivery (USB PD) Specification enables the maximum functionality of USB by providing more flexible power delivery along with data over a single cable."

The interesting bits of the spec use extra pins from Type-C, so for the most part it's Type-C's charging norm.

...and even aside of USB PD, USB-C The Connector does have a standard way to signalize maximum charging current (0.5/0.9A, 1.5A or 3A at 5V) without using PD.

PD predates USB-C. It works over any USB cable, with appropriate limits for old cables not originally designed for it.
