Since the selftests are shipped with the kernel code, I think
we don't need to handle backward compatibility here. Instead,
we can just assume disabling ftrace is no longer supported.

Incorrect.

I tend to agree but I think here[1] Steve and Miroslav asked for
backward compatability. V1 was actually the way you prefer.

Right. We test older kernels (think LTS) with newer testing environments.
We need them to be backward compatible.
