Well said. And we're not even mentioning what happens when you start adding other criss-crossing traces for parallel LCDs and cameras into the mix. Those usually creep into the 30-40 MHz range, 18-24 lines per device with no differential lines. And I haven't even thought about USB-C yet. And you still need to pass radiated emissions testing. Even those right-angle DIMM connectors for the SOMs spray RF noise everywhere when you put video on them.
