That is a > requirement for any overlay in the tree. You mean apply for testing purposes? How, technically? Or is that about actual usage by the kernel? I was sent here from a U-Boot discussion where we would like to consume all DTS files from the kernel [1]. In our case, the kernel will not use these overlays, the firmware does, presenting the result to the kernel during runtime.
