Sure, it's always painful to add new dependencies. If adding a new dependency 
buys us a tremendous amount of comfort, I'll happily do it. However, this is 
only a convenience thing for whoever changes the dts. And every change to the 
dts should go through upstream. And there I'll generate the dtb. :)

Yup. Worst case we'd keep around a minimal dtb that doesn't need to be modified 
too often, but yes.
