The MPL is all about training a machine operator not a pilot. It is also a mechanism for reducing cost for the airline. In days gone by, airline would employ instructors with 700 hours plus needed to get the cpl. In gaining these hours they learnt not only the mechanics of flight but also CRM. Also you learn about people and what they are like under stress and how to both deal with and mitigate the negative factors that stress brings. I think instructors are an undervalued resourse but who am I to say.
I am ex instructor and single pilot air taxi in Seneca Navajo and had no difficulty transitioning onto a jet.
