Yes! WKT is a very handy open standard for expressing spatial data in text. It’s also useful because multiple spatial types (point, line, polygon, etc) can be expressed in the same CSV or spreadsheet file instead of split across multiple data files by type as is normally the case in GIS data files, which makes it ideal for Kobo form data.
For example, if a Kobo survey was exported as a CSV and included multiple WKT types, a user could then first open this in QGIS as a point layer, then open the file a second time as a new layer as a line layer, and even a third time as a polygon layer. Then if any corrections or edits needed to be made the data, it would just be done in the one CSV in a spreadsheet program and the changes would be reflected instantly for all three layers in QGIS.
