I have to point at the following threat: a dynamically allocated ID may 'squat' a bus ID that intended for a device with statically allocated ID. This scenario is possible since module loading order is uncertain. This threat seems to be inevitable...
For DT systems the dynamically allocated IDs start at the maximum positive ID and work down so in practice it is vanishingly unlikely that there will be a collision as idiomatic static DT IDs would be low integers.
