Do we need "Bombay to Mumbai" type conversions every year?

It has become so common nowadays to see changes in the name of cities, streets as well as states in India. Every time I see the news "Union Cabinet has approved the change in nomenclature from xyz to abc", I find it so odd. People are so used to the earlier names that such a sudden change brings real chaos. Someone says correctly that everything was done by the British, we just keep changing the names. I agree that, some regional sentiments are attached to such changes. The names given by the British to the cities, states may not sound like the way it should be according to the language specific to that state. But why no one was there to think about it before? Its more than sixty years now since India got independence and now people are becoming desperate to change everything. They don't even realize how long it will take for the new name they give to become familiar to the world. For example if you change the name of a fifty year old institute like IIT Bombay to IIT Mumbai just because some political parties change the name of the city from Bombay to Mumbai, people would find it very difficult (specially abroad) whether these two names correspond to the same institute or not and that will surely gonna affect the academic part. But no matter what happens to the institute reputation and popularity, political parties will change the name for sure sooner or later. Today I have seen "Orissa is now Odisha, Oriya becomes Odiya" in Times of India which is just a replica of Bombay->Mumbai, Bangalore->Bangaluru and many others. I remember people in my state were also proposing the change of the name from "Assam" to "Asom". I am however not in favor of it. Basically the true ethnic pronounciation is neither Assam nor Asom. It is just a convenient way to write since there are some letters in Assamese alphabet which are pronounced in such a way that there is no counterpart in English or in Hindi. People write those alphabets either by using "s" or "h" in English. Thus although change in such nomenclature may have some correctness in the case of other states, this is not the case with "Assam->Asom". May be we should better stick to the earlier and most popular name of our state. Personally I feel, its the people of the state who have to carry the true identity of the state they belong to and their ethnic culture, not the name of the state.
