It almost doesn't scale right now and that's just qcom designs.
At that other company the various dtb's that was to be picked for a given product was always to support the various SoC versions; so those devices always shipped with the mtp board-id and msm-id.
As far as I've seen this is how Qualcomm's Android customers does it.
But as things progress further I do see a need for being able to also pick the right product and at that point you're right that the vendor must change their boot loader.
