I'm not sure what that adding and removing is referring to, but why
would this new code be needed to handle the sae_pwe parameter when that
is already covered through the generic mechanism for the SET command to
set global configuration parameters?

Why would this be needed?

This ends up doing practically same based on the global_fields[]
array providing the global parameters, including sae_pwe.
