This is an interesting question. I would add a couple more issues. My company has excessive tailwind on touchdown as a Foqua item. If you bust it by enough you will get a polite enquiry from our safety pilot, who by the way is a good guy. But you still need to explain yourself.
It is tricky providing evidence that the tower gave you a different wind then the one the plane recorded on landing. You can ask for the tapes but unless you crashed (in which case you have bigger problems) good luck getting these from some military tower in southern somewhere.
Also the issue of gusts and wind varying complicates matters. In theory the gusts may not be limiting. In practice a ten knot crosswind with twenty knot gusts that at the the moment of touchdown are mainly tailwind can be difficult to spot.
The simple rule if in doubt is to go around. The example from Full Wings demonstrates why this is a good idea. We do not have to explain ourselves if we go around, but we do if we bust a tailwind limit, which I think is the right way around.
