Sure, but I had the understanding based on our last communication that
you are going to go with partial support for now and multiple domain
thing will be done later on.

Right.

Even on that I thought that you will artificially vote for a high
requirement for those devices from some platform code initially, and
remove that code once all the device drivers (you need) are updated to
post their own requirements.
