A funny thing: I’ve spent a considerable amount of time in Mumbai, and there definitely seems to be a significant number of native residents who still call it Bombay. It was to the point where we briefly wondered if this was referring to two different parts of the same city (south of the Sea Link bridge is Bombay, the rest is Mumbai, maybe).
Names are complicated! Germany/Deutschland, Holland/The Netherlands etc.
Interesting that Wikipedia keeps “Turkey”: https://en.m.wikipedia.org/wiki/Turkey
They also keep Gulf of Mexico.
As a programmer: localization is a PITA.
