No, it's not. AF put no pressure on the pilot to 'push on' its the PIC responsibility to manage their pax, regardless of how happy/unhappy they are. As nev said it's a lesson for US in HF. This is where experience comes into it.
There is also a large difference between multi crew ops (which this would never be for private ops excluding the citation) and carrying a second pilot. An inexperienced pilot carrying a second more experienced pilot COULD be a good idea for some but shouldn't be mandated because as I said there is a broad spectrum of pilots. Where you get into trouble is with two inexperienced pilots, one can easily reaffirm the others poor decision making.
