The A300-600 was the first aircraft where we encountered increasing thrust at acceleration height, Airbus solved this by limiting the thrust reduction to 25% OR CLIMB THRUST, I'm pretty sure that Embraer does the same thing.
As a sideline anecdote .. nothing new here.
Wal Stack (the QF ops eng boss back in REALLY olden times) related a tale concerning the very earliest days of reduced thrust takeoffs (QF was one of the initial leading lights).
Appears one of his 707s launched to wherever ... crew came back and raised the point that, at thrust reduction to climb power, the FE had pushed up the throttles .. and the Commander thought that a tad strange.
Whereupon Wal had a direction issued to limit takeoff thrust reduction to the intended climb thrust setting .. which made the spectre go away and kept his operating crews happy and contented.
One of the advantages of having an (ex) operator running the ops eng show.
