Surly the ultimate limiting factor is turbine temp. If you put too much fuel in before the compressor has had time to spool up then things will over temp.
To quote an old book title on my shelf, "It all depends".

A modern high-efficiency compressor might be quite happy at steady state conditions (TO, cruise etc) but have little tolerance for a transient over-fueled/over-pressure condition. It stalls, and when it stalls, it's like a Harvard stalling with crossed controls - only more violent.

OTOH, a brief overtemp by itself might not cause immediate big damage, but if the operator expects to keep that engine on-wing for many thousand hours and cycles, o/temp is definitely to be avoided.
