<desc> This variable determines the method used to couple MOM6 to WW3.
The method "most" corresponds to the newest coupling method
that turns on FPMix parameterization, Stokes_Bands coupling,
and Stokes similarity package. The method "legacy" corresponds to
the older coupling method based on receiving a Langmuir number from
WW3 and passing it to CVMix. When set to "none", no wave
parameterization is used.

Please revert LAPLACIAN to True. We will need it for the LEITHY backscatter, which will be introduced in an upcoming PR.
