It's non-existent and imaginable only because you've been ignoring
everyone that said that you should do it. So it's self-inflicted,
really.

And the DT is considered an ABI, so yeah, we will witheld everything
that doesn't fit what we would like. Your point of view is that it's
more work and for no particular benefit, ours is that it's a
short-term pain for a long-term gain, and the benefits will be in the
maintainance cost.
