More importantly, you might want to update the fdt files on a different
cycle than the kernel. If you have a new slightly different configuration
in a new machine you want to support, it may be easier to add a new file
somewhere than doing a respin of all the kernel packages when they
contain the dtc source. I would not see much of a problem with always
shipping all trees with the kernel package, even if they never change.
