Careful Wizzo!!
It is well known that the B767 for one can often be way above the brake energy limit in an overweight landing. Recall that Vref will likely be well above V1 and energy is V*2. Think about the engine uncontrollable fire scenario with F20 landing required.
In general what you say is, of course, correct but there are certain a/c types and certain runway lengths which will cause a very surprised look on the faces of those who haven't done their homework!!
Naturally if you, Captain, decide on the day that you MUST land NOW then just do it and maybe bust up the airframe as you depart the end of the runway. With any luck all hands will be able to run away to fly another day and you will have satisfied your primary responsibility to the pax, kept 'em alive.
