Uggh. That's going to make the device tree files look different between
the kernel and U-Boot:-( With # disallowed in particular, it's going to
prevent U-Boot from /ever/ using the correct protocols for parsing the
device tree. This seems like an extremely bad idea.

That looks extremely unlikely in its current form. Ideally, I will get
time to take Jon's or David's patches and push one of them forward to
provide a more complete solution, but it's a very long way out either way.
