It wouldn't apply to them in the same manner given context, but the R>F stuff applies to the dimensions in K3 at least.
If you're arguing that it wouldn't apply to, say, Paradise Lost, then sure. We can discuss that later. But it would apply to worlds past Mercurius' as their worlds have their own similarities. Masada applying different religious philosphies and concepts in the cosmology doesn't really change that. You'd also have to prove that Shinza has multiple different types of dimensions.
Like I said, I personally think this discussion is best suited for a separate thread. This thread should be for, and only for, bringing the profiles back. We can discuss what the revised tiers should be later. That requires its own CRT. But yeah, you do make a good point. But I believe that someone made a point that higher dimensional beings in Paradise Lost can instantly obliterate lower beings, with higher dimensions being completely inaccessible to most people. That's just something to note.
If you want to really go into the whole R>F stuff for Sefiroth, the other thing I could think of is the fact that it's a hierarchy from the universe to the throne. The throne being the thing that transcends everything else in the cosmology. That's also something to consider
