It's so common that it's not an unlikely starting point. EMC is a major issue in high frequency electronics design and the raspberry pi had a history of having to redesign certain parts because of not having enough shielding.

There doesn't seem to be much info on compliance out there for Pi 4 which must have been significantly different w.r.t HDMI.

Absolutely, and this was before the Pi had built-in Wifi. The norms you have to comply for are immediately a lot stricter as your device falls into a different category (telecommunications devices).
