Eh? I hate to say it, but your comment reads a lot like FUD.

First of all, I think you're confused about how the DT bindings are created -- there's no "committee" or "outside 'experts'" involved. Yes, there's peer review of bindings, but from what I've seen it's been mostly technical.

Then, you're ignoring the fact that DTs work very well for a large number of boards. Yes, there will be new types of devices that need new drivers ... invariably, boards don't just get faster! But they still include a plethora of standard devices. Serial ports, RAM, IRQ routing, PCI(e) busses, etc. None of that is usually re-architected every time a new board is created, that would be way too expensive!

As a result DTs can (and in practice do, I've seen it done) solve a large percentage of a new board port, up to 100%.
