Avi Loeb gives a simple argument that there can be no $(Dω)^{1/2}$ enhancement: since the problem is linear in $h$, one can decompose the GWs into plane waves and for each of these there is no enhancement.This paper was incorrect in that it drastically overestimated the cumulative deflection due to a gravitational wave background.
