     We discuss several corollaries of this observation, including the interplay between the upper bound on the scale ${\displaystyle M}$ and the order parameter ${\displaystyle \epsilon }$ associated with the breaking of dS symmetry, and the possibility that the relaxion could play the role of a curvaton.
