not sure how (if at all) flight deck automation has impacted this, but in the days when crews had to carry paper copies of the airplane flight manual and look up takeoff distances and speeds on the pages of performance curves, the data only went to 120 degrees F and could not be extrapolated for higher temps ... the pilots had to wait for the temp to drop before taking off
