Well Known Text is nice, but straight up latitude and longitude can be read directly by many other tools. IE, if you want to upload a CSV to CartoDB or ArcGIS.com or Fusion Tables, or another web mapping service, these won't read or parse a WKT column but they will pay attention to two columns with latitude and longitude.
Yes, shapefiles and KML are alternative export options, but as they currently stand trees and plots exist in the same shapefile but as two different attribute tables, which similarly makes mapping them with non-advanced tools difficult.
