What is a major implication of this deep water storage on planetary geology?

Answer

It affects the viscosity and temperature gradients of the mantle, influencing tectonic plate movement

The presence of water affects mantle viscosity and temperature gradients; if water is cycled down during subduction and released later, it influences the long-term movement of tectonic plates.
