Short field landing techniques are in fact regularly exercised, planed and executed everyday in airliner's lives: You are close to your required landing length, so you choose maximum flaps, minimum speed increments and use the most useful type of approach. If you still cannot make it, you have done something wrong before and shouldn't have departed anyway.
The short runway problem anyway is rather a problem in some countries, of which Indonesia and Australia seem to be suffering more than others, something I realized after having flown there for years. In other parts of the world, especially in the western world, runways are normally pretty long, 3 to 4 km, which is enough for every type of aircraft.
It still doesn't get into my head why in these countries they use so short runways. It's clearly a lack of public infrastructure, and it would be much cheaper to have long runways than accidents. Those countries shouldn't also have problems with land ressources, something in Europe is the biggest problem with airport extensions.
