    22 We can do it temporarily to see if it resolves the issue, in order to gain some intel. I am strongly against this solution as a permanent feature, since it would kill the performance of simulations using the kinsol solver to solve algebraic loops and then some ODE solver for the differential part. It is not the case of power grids, but it would be the case, e.g., for thermo-hydraulic grids with incompressible fluid.
