However, normalized read noise is not photographically relevant; and the DxOMark Landscape Use Case score is supposed to be a photographic use case.

Read noise is not relevant to whose photography specifically?

I think I could have been more explicit.
I mean that a measure that is solely read noise and has no photon noise component is not photographically relevant. (It has engineering relevance.)

At how may EV of (in-processing) "pushing" do the results cease to be "photographically relevant" ?

No amount of pushing will be relevant in an area of the image that is entirely read noise.
This is equivalent to an infinity stop push and even at infinity I suspect that in this case 0 * infinity = 0.
