Bellerophon
Fully agree with your point regarding thrust on approach. My point is the increase is largely irrelevant regarding the points made in the original question.
For every 50kts of extra headwind the rate of descent changes by only 250 fpm (at 100kts airspeed on a 3 deg GS). The amount of extra thrust required to maintain that ROD for the short amount of time that the aircraft is on the approach matters little in the big scheme of things.
Again, in answer to the original question relating to the differing thrust on touchdown, the extra thrust is more than compensated for by the reduced groundspeed and so even with the (small) increase in thrust your touchdown speed will generally be reduced.
I tend to agree with Oz. The biggest problems with strong winds occur whilst on the ground.
