In one of my previous airlines (B757/B767 operator) our training was to treat all engine failures on take off as severe damage. With no fire indication the fire switch was pulled but the extinguisher was not discharged. If a relight was subsequently determined to be desirable then the fire switch was simply pushed back in. This allowed the relight envelope to display on EICAS and the only thing that had been lost (in addition to engine thrust from the failed engine) was a associated engine driven hyd pump which had been depressurised and would need resetting after landing.
