ATIS gives "planning/long term" info which improves our situational awareness as to what might happen. Reports from ATC by recent measurement and/or experience of recently landed aircraft (which we often get in windshear conditions) allow us to finesse the decision.
Whilst we (I) like to operate as efficiently and safely as I can, there comes a point when margins between being efficient and ensuring I'm stable dictate that I will take the "easier" option and just go flap full. However having additional info available would be of great benefit. Perhaps we could get it in Spain when "wind calm, clear to land" usually translates to a 15 knot tailwind in short final and about 5-10 tail during touchdown....
