Jim,
It is a gimmick with no real point!
This was merely implemented as a response to a popular request from a considerable number of pilots who asked for shorter flights for class 7. Our thinking is that it needs to be as realistic as possible which is why we opted for the VERY limited maintenance schedule as suggested by Christophe Moutot
Here. Let's face it, you don't see many 747-400's flying a schedule from London to Frankfurt with PAX on board. This way we have a realistic way of implementing it as many RW airlines perform this sort of movement.
In the future (distant future at this time may I add) when the ProPilot system is developed to the next generation with failures and maintenance, we will be utilizing these flights for positioning aircraft to EDDF for routine and essential maintenance.
Sorry if you don't like what we have done, I hope it doesn't inconvenience you in any way.
Regards,
