Airbrake,
Don't really agree with you that pushing the throttles to max is only done when you porked it up or to be used by Hollywood.
The SOP's my colleagues and I operate to require us to select TOGA after an engine failure on take-off. This is one of the first steps the PNF does when this emergency arises.
The aircraft involved are both the minibus and the bigbus and even without selecting TOGA on the remaining engine we still make the requirements. However it gives you just a bit more performance.
And firewalling the engine is no big deal as (with no failures in the system) the FADEC looks nicely after the engine and prevents any excedance's.
