Do you have an example for such a "USB-C edge connector"? Intuitively I would have said that common PCB thickness is too large, or do I misunderstand what you mean?
Yeah, you need a 0.8mm thick PCB, but everyone can do that now (JLCPCB and oshpark both do it for the same price as a regular 1.6mm board). Here's a footprint: https://github.com/jmgao/PCB-USB-C
