In my industry there's no standard if a position should be latitude,longitude or vice versa. Every tool wants them different, it's easy to have them mixed.
I agree it is pretty niche. It might be nice to support non-WGS84 coordinates
- EPSG:3857 Web Mercator
- EPSG:6933 https://nsidc.org/data/user-resources/help-center/guide-ease...
- UTM
You could just support Web Mercator, if normal or swapped are not valid coordinates, assume Web Mercator and check if they are valid coordinates. If they are swapped it will still be in the general area even if the projection is not exactly matching
