Yes, this is a problem. ARM SystemReady certification program is aiming to solve it. Unfortunately the only boards that meet this certification are significantly more expensive.

For example, Honeycomb LX2 (https://www.solid-run.com/arm-servers-networking-platforms/h...) -- very solid, great specs, upgradeable RAM up to 64 GB, but its price has been increasing over time, now at $919. Still, looks tempting to me.
