My patches don't change where the dtb goes as far as I can tell.  If
there's a problem, it can be addressed with an additional patch (or if my
patches do change it, please tell me how).

I can see potential benefit in allowing multiple dtbs to be included, to
be chosen at runtime (such as from a board ID passed from the bootloader,
or based on detection of how the board is configured (such as detecting
whether an MDS board is plugged into a PCI backplane, or is acting as a
PCI agent, or is standalone)).  But why all of them?
