This is not my area, but how does your statement reconcile with [1] and [2]? [1] "The fate of water within Earth and super-Earths and implications for plate tectonics," doi://10.1098/rsta.2015.0394, from which: "Water is thought to be critical for the development of plate tectonics, because it lowers viscosities in the asthenosphere, enabling subduction." [2] "The role of liquid water in maintaining plate tectonics and the regulation of surface temperature," 2001AGUFM.U21A..09S, from which: "The difference between the strength of a wet lithosphere and that of a dry lithosphere seems to be big enough to control the very existence of plate tectonics."
