If one is going to implement Julian-to-Gregorian calendar cutover, one ought to make it location-specific - this date is only correct for the former British Empire. If one doesn’t have location information for a date, the only sane default is the first cutover at which the calendar was initially introduced, October 1582, which is the cutover date for Spain and Portugal (excluding their colonies), most of Italy, Poland and Lithuania (albeit, borders were different back then, so none of that exactly corresponds to the modern countries with those names.) To instead default to 1752 is a regrettable form of Anglocentricism
