I'm not sure how any rep can say they wouldn't countenance a work to rule. Last time I checked EU Ops and EASA Part 145 you have to raise a tech log entry for an unserviceability. It is EU law.
There has been more than 1 accident in the past based on the glorious phrase "it'll do a trip". I know that snags are carried through until the end of the day but technically it is illegal. I'd like to see your rep get that phrase past the CAA.
