Not really because the easa regs are made by a bunch of lawyers.
I think the reg is that you need 750 hours IFR time before you can operate a SPA commercially.
Those that are flying multi crew don't care about it because it doesn't effect them. And those that already have it don't care either.
Multicrew jobs are hard to come by.
There is also a requirement for IFR time before becoming a instrument instructor.
So for your vfr ppl instructor with sub 100 hours under thier belt IFR its virtually impossible to go to single pilot commercial ops. And once someone is in multi crew ops they have no interest going back to single pilot ops or for that matter instrument instructing.
So there is now openings in spa operations but no real supply of fresh meat to sit in the seat.
