I would like to think that it is quite common. Certainly for guys who provide lacquer/DMM cutting services.

There is an issue with vinyl brokers and certain unnamed plants that advertise "mastering" that consists of running any delivered audio through proprietary software that "fixes" all physically problematic issues that could affect cutting or playback (excessive sibilance, excessive negative stereo correlation etc.). There is minimal listening involved and they can cut almost any audio. All optimised for maximising the factory throughput, not sound quality.

Personally I have a hope that this will become less of an issue in future as vinyl is getting more popular and people little bit more educated.
