This is called timely reformation in the different rituals and custom of any practicing religion, what shani shingnapur temple shows us, after all the long ban over women's entry there, it was ultimately lifted. There were lots of ill traditions, associated with Hinduism, but they all are being averted. Though, still lots of thing have to do over caste rigidness. So the thing is that one should have always open window for fresh air and space for reshuffling of any ideology and organisations.
But why this is not visible with Islam. One who think that they have built a glorious fort and it is never required to be cleaned, they are in illusion, every sort of organisation, ideology or way of life scientifically needs reformulation and reorientation, but it should be strictly done in the respective domain only
