I agree with Nooby
In any case do not forget that an engine is not just an assembly of compressors and turbines!
If there is a possibility of foreign material ingestion (even with no scratch or dent on the compressor), all the air system, pipes, pressure sensors,etc. must be duly checked. You never know when the least expected piece of fabric will be stuck into an air tapping, a pressure sensor, an oil jet... ruining your long over sea night transit!
Being a bit conservative never reduce flight safety level!
