Generally I like this idea, but it breaks the existing users environment and doing this sharp cut might be annoying for the phase where you switch between different barebox versions which could be quite common for development boards. Would be great to have a grace period in which we prefer the UUID environment over the device tree environment (we might do this already) and warn in case we still use the latter. We could stick the warning to a device tree property like "warn-deprecated-env" and remove the environment once they carry this property for a year or so. Just the ideas from the top of my head.
