@9.G, on the Boeings I've flown it is a mandatory full thrust take off as well if windshear is suspected or reported (which usually means bigger thrust increase as normal take offs usually use thrust reductions greater than 30%), and of course they have the full suite of predictive and active windshear warnings as well. Some of those pws warnings are inhibited during take off though, new caution alerts between 80kts and 400ft AGL, new warning alerts between 100kts and 50ft AGL, existing alerts remain active. Nothing wrong with using that 30% extra thrust on the ground to gather some energy in the form of a few knots more speed before attempting rotation, it just provides a bigger energy margin during the event.
