Given that this is really a don't care for the kernel, I'm not sure what
kernel change you are thinking. It is not the kernel's job to validate
the dtb, so I think the kernel should not care. We should do this sort
of validation at dtb build time at the latest. As to updating the dts
files, yes we should probably do that.
