It is an ongoing debate, but generally they should be considered ABI
and follow the ABI rules about not breaking backwards compatibility.

However, there is also an argument that something like a NAS box
running Debian is going to use the DT blob which came with the kernel,
so deprecated DT properties and the code to support them could be
removed after a period of time.
