However, India is neither a sovereign nor a nation.
India's languages, unlike Mandarin, have been reduced to a state where they have zero, if not negative, economic value - which is why even day-laborers scrounge together money from across generations to put their children through India's British-era clerk-factory education, all to mindlessly memorize & "wordcel" until they pass a Govt. exam. Like a bad GPT-1 era LLM.
Those who gain knowledge while going through this horrible, dehumanizing "civilizational" pedagogy (one author calls this linguistic apartheid), will for obvious reasons, migrate to the "real" center of their being, which is the West.
If you look at Sarvam, GoogleAI, MSRI .. & other "social AI" projects (along with technocratic things like Aadhar etc.), they begin with a other-ing of the vast population first and try to solve these plebs' problems as they see them. This doesn't work, because it's essentially a Indian elite version of the white-man's burden.
Eg. Nilekani who is behind AI4Bharat was the head of Aadhar - a project that causes numerous issues to this day because it uses (surprise surprise) Latin encodings for names/places etc. instead of Brahmi-Unicode blocks or IAST. India (rather strangely) doesn't have a standard transliteration scheme, so every one and their pet-dogs have their own transliteration schemes, and will write their names differently at different periods of time. This even if they'd write it the same way in their own regional Brahmi-derived local script! Aadhar centralizes Govt. services massively, and so any change stemming from this linguistic-imposition of English across services requires travelling to a number of offices along with the usual kowtowing. All this ignoring how this is changing languages themselves, given that these languages typ. have more nuanced vowels / consonants compared to latin.
In 1-2 generations, India will not have much left in terms of linguistic diversity given the policies of the same ruling elites, so all this seems moot IMO.
I'd ignore all talk about "civilization" / IKS ... - such folks incl. politicians/bureaucrats can't spit out a single coherent paragraph in their own mother tongues or in their "civilizational" Sanskrit; their children likely are mono-lingual in English like the very British/Americans they try to gain "sovereignty" from, but whom they'll eventually join (eg. the current education minister in Karnataka can't even read Kannada).
The Indian elite have had this horrible disease for centuries - the Marathas/Vijayanagara etc. managed to overcome the Timurid empires that were running amok in India, only to mimic them to the point that their own armies ended up being run by these same people. Gandhi/Nehru "overthrew" the British, only to create a vestigical "mimic" empire that kept every goddamn policy and worldview of the British intact, turning the country to the biggest Anglo-Saxon country culturally/linguistically (and if our friends have their way, religiously).
