Same DOF on both systems, which is not necessarily optimal if the scene would have been within the DOF at f/5.6 on FF.

Yea, the lens is petering out by f11 a s well

no pun intended

Seriously, though, it's not that the lens is "petering out", but that diffraction softening is outweighing lessening lens aberrations.  That said, all systems suffer the same from diffraction softening at the same DOF, but do not suffer the same lens aberrations at the same DOF, so the overall captured detail at the same DOF will not be the same.
