Yes!! There is one core and many peripheral reason to it.
I come form a geographical area where "meena" community is the most dominant class - much above traditional Brahmanical order.
They are the most uplifted class in Schedule tribe (ST) pan india
Economically , politically , socially , educationally.
There is no match for the magnitude of the good reservation has done to them.
One can take it as a model for pan india upliftment of a tribal class.
