Weak definable amenability conjecture for discrete definable groups

Let GG be a group definable in an arbitrary structure MM. Write GM00{G^*}^{00}_M and GM000{G^*}^{000}_M for the model-theoretic connected components of GG^*.

Weak definable amenability conjecture. If GG is weakly definably amenable, then

GM00=GM000.{G^*}^{00}_M={G^*}^{000}_M.

This is the discrete specialization of the generalized definable topological amenability conjecture. The supplied text presents it while discussing that specialization and gives no resolution status for it.
