This is a licence brought about after considerable research into improving training for ab-initio pilots moving straight onto jet transport aircraft.
I disagree with the premise. The "research" was more accurately into improving [reducing] the cost [to the airlines] and time for ab-initio training. The training may provide a stopgap measure for airlines who need FOs to fill the right seat, but it fails to provide a long-term solution to the pilot shortage in the affected countries. Those MPL pilots will be ineligible to serve as Captain, so the future searches for pilots who have the experience and air sense to become Captains will become even harder.
