Each binary will vary only because of different machine features, so if Q and DL have the same features, the binary will still be compatible. Do I misunderstand how this works?

Yes; see the packages generated and how we enable the MACHINE_SOCARCH;
it shares binaries across same SoC families[1]

So what would happens is that all recipes we have on -mx6qdl would
change and be MACHINE_ARCH. This is a bad side effect.
