In other countries where MPL is employed, it is the exception, not the rule. The MPL pilot's skill level is supposedly on par with a CPL license holder who also did a type rating on FAR/CS25 aircraft, but a lot less time in airplanes and much more time in simulators. MPL holders cannot exercise single engine or multi engine privileges (outside of their type rating). MPL holders are restricted to flying aircraft for one certificate holder and can't switch companies until they have gained an ATPL. Lufthansa found this to be a limitation since they operate multiple certificates and had no flexibility to put their MPL pilots in other certificates and reverted back to the CPL path.
