Yes I think the return of the none "professional" pilot (the CAA term for those with a PPL) teaching students is being debated as part of the usual "port-and-wine-by-the-fire" meetings at the Belgrano driven by those with a vested interest (e.g. school owners seeking to reduce costs)
That will make those planning to complete a fATPL more likely to contemplate the MPL which puts you directly onto the flight deck rather than being paid peanuts as an FI building hours in the flooded market of PPL/FI.
