Deduplicate the diff please. Something like:

-GREATER MUMBAI
+Mumbai

Don't need to know the remaining fields, just a unique list of districts impacted by the change

What's the coverage of the change? (How many districts are matched, and left unmatched?)

Don't think we can merge this till we're sure about the accuracy of the data.

In the meanwhile, I've found a nice source for an official list of districts india, with district codes that we can perhaps use. https://lgdirectory.gov.in/. Here's a cleaned up version: https://github.com/planemad/india-local-government-directory/blob/main/administrative/2-district.csv

It's missing a few districts, I've filed a PR for that.
