I guess there are several reasons:
1. MIDI didn't block everybody which means time to time, there are ppl randomly get CSQ (with no predictable pattern )
2. as far as I know, there are some ppl did/ said/ even may or may not brought a lawsuit against MIDI and got no positive result
3. you have to admit that MIDI has the final say, now they probably got way more applicants than before (especially in the PEQ-graduate category) so that they have to/ can choose the best one and who's french is better than French? I guess nobody... and French ppl have the most similar culture background, most of them they apply through the PEQ-worker which means they have a at least regular job. So it unfortunately make sense that French applicants are not influenced by this delay. Also, I can imagine majority of the PEQ cases are french or at lease francophone applicants, so from the big picture, PEQ has not changed at all.
