NOC based cutoffs will start coming in future definitely. EE is a nascent process and was just started in 2015. They will make changes as they learn more and make it more matured. From the learning of 2015 and 2016, they found that 600 points for LMIA was getting abused by cooks and fraudulent cases, so they made it 50 and ensure that even LMIA candidates have high human capital. Likewise to help students (who are best possible fit to their country), they gave 15, 30 points. We can definitely expect something on occupation in coming years if the see particular occupations overcrowding the system.
Like in Australian system, the cutoff for most professions are 60, for IT related professions it is 65 and for some other professions like accountants it is 70.
