A common request I get is to surface the latitude and longitude of spatial data as attributes for ease of use in online data tables and pop-ups. The most timely way to do this is an Arcade expression in either a pop-up or attribute rule to calculate the values. This currently requires the user to compute the transformation themselves, which is error-prone and difficult to read in the context of an Arcade script.
My request is a way to get lat/lon through built-in Arcade functionality, either through functions or properties on the Geometry object type. Only supporting Web Mercator data sources is great as a first step but supporting all projections would be ideal as this increases the portability of all scripts. This would require support for both the Attribute Rules and Popup profiles for my use cases but could be expanded to many more profiles.
I'd also take implementing this projection idea as a suitable solution, although adding lat/lon access as a convenience on top of that idea would be even better.
