They are independent the same way NFS v4 is independent from NFS v3 and
v2. Independent but related, and most importantly, one is the fallback
of the other.

If the result is that the fallback work without user space intervention,
then I agree with you.

independent and this fact need to be properly considered and factored in
into this decision, nothing more, nothing less.
