I would not exactly call what we have for powerpc "exporting the OFW device tree". I don't quite know what it is, but it isn't as simple as exporting the OFW device tree. I don't think we really wanted to get into any of that here.

Sure they can take advantage of it, if what they need to export is a read-only copy of the actual device tree without any legacy burden or having a writable/changeable copy of it with a trivial implementation. But that's not up to us, and that's not what's been done for powerpc and sparc.
This is a trivial implementation that suits it's purpose. It's simple. I'm not sure what more is needed for this project when it's pretty clear that i386 will never need any additional support for open firmware.
