No. This is *not* a bisectability problem, as it has been established that device trees and kernel code shall *not* be built and deployed together.
Consider:
- Just subsystem changes are merged: OK you can still take your DTS from somewhere and boot this kernel with it.
- Just the arch/*/*.dts[i] changes are merged: OK these new DT nodes remain unused, presumably the system survives anyway?
It only becomes a problem if you also start to apply patches deleting functionality that has been moved over to the device tree in the same merge window - don't do that. Take a sweep with the broomstick next time instead.

I don't understand this. First you say it is prone to broken bisectability, then you say it is not coupled? Isn't this the same thing?
