I can think of multiple operators who operate >5700kg turbine aircraft on CHTR ops, multi-crew, on occasion with 2 x CPLs crewing the aircraft. One logging PIC, one logging co-pilot, or possibly ICUS from time to time. I can think of another handful of operators that crew single-pilot aircraft (B200, C441, C404, PA31 etc.) with 2 crew to meet contract requirements. Not always an ATPL up front.
Maybe I'm missing your point.
