The grandmasters commentating at major chess events do not use chess engines. This is because it's more interesting to hear their human analysis, which helps over-the-board players to develop their own analytic skills further.
So the goal paradoxically is not to find the absolute best answer in a given position: but to practice strategic analysis, which can perhaps best be done in a concrete position.
Such strategic discussions of interesting positions are a valid part of the chess.stackexchange experience. Even though I am not really an over-the-board player, I would always vote to keep such discussions open.
