Design flaw in current Pi hats?

[madeofstown]

In the process of designing my second LoRa Raspberry Pi hat and looking through wiring schematics, I discovered that every existing hat that works with meshtasticd (including the first one I designed) doesn't appear to use the correct GPIO for CS. Every design I saw used a generic GPIO pin for CS. I would assume that it should be connected to one of the CE pins for the SPI bus it is using.

Can somebody please correct me if I am wrong about this? I realize that the hats function but I'm wondering if they may not be working in optimum conditions.

I have been able to briefly test my new design and the radio works fine while using the Pi's CE0 pin as its CS pin. I need to do some better testing before I can say if there is any improvement in function or performance.

I would really like somebody more experienced in these things to tell me why this isn't an issue.
