Device Trees are a way for the System Administrator who installs an OS on the system what hardware exists.
It's far more likely that the hardware manufacturer is going to accurately identify what hardware exists than it is that the System Administrator is going to know what hardware exists on a system.
Device Trees may look like they are discoverable if you are only looking at it from the point of view of an OS that has the Device Tree provided to it. But from the point of view of the person trying to install the system who has to figure out what to put in the Device Tree, they are not discoverable, they are the output of research, not the source of information.

ARM vendors don't really care about Device Trees, they are pretty happy just hard-coding the kernel itself.
it's the people who want to upgrade the devices and people who want to maintain the upstream tree that want the consolidation made available by device trees.
