The intentions are undoubtedly good. But the actual results? Every government department is horrifically inefficient because a whole lot of people who do not know how to do work land up there due to these quota systems. In many cases, if you fit in a special category, you can basically fail in your university entrance examinations, even not attempt more than one question, get that question wrong, and still get admission.
People regularly riot, often violently, to pressurize the government into declaring their group as minorities so that they can specifically get these benefits.
ISRO and the Army are the only public institutions in India that operate on meritocracy. And they are pretty much the only public institutions held in any regard by the public.
This may have a feel good effect in the short period and some people may feel like they are somehow morally superior. But this will always lead to a whole lot of pain in the long term.
