The problem with the question form "why didnt you just do ___ here?" is it's loaded with the assumption that the other party should have known to do this other thing instead.
A better approach is to use the less loaded "have you considered doing X here?".
If you find yourself needing to demand others not take offense at your questions, you might wish to try a different approach.
