The very fact that you feel that the approch requires something which is not done is a message that you shouldn't be landing there. Short runway, limit tail wind which could easily go over the limit, heavy rain can make the braking action poorer than imagined and control of flight path difficult these are too many variables which can prevent a successful outcome. Not a safe decision to continue the landing.
I am aware of the realities we face in day to day operation, I am assuming we have a valid landing performance. With good visual references and decent knowledge where my under carriage is, I could easily buy myself a couple of hundred feet. What if the undershoot is a displaced threshold? As I said, not everyone's cup of tea.
