Just like the RPi, no plated mounting holes for grounding. I am curious if there is a valid reason not to use grounded mounting holes.

It is not easy to pass EMC tests if you want to embed these boards into some device without proper grounding.

Is it possible that they might be relying on mounting frames for metal enclosures or wired grounding near the power supply connector, just to avoid ground loops?

Ah I guess. So you would design a custom frame that connects electrically to the connector housing(s).

Might be a good accessory to sell.
