I don't think that the intention would be to make the re-emergent PPL/FI the sole route in the future; rather it is to facilitate the aspiration of part-time FIs who are happy to teach for a couple of days per week at a RF but don't want to become full-time commercial pilots.
It's up to those who want a PPL/FI back to propose a suitable course - I doubt whether it would ever be any 'easier' though!
