One good reason is that it's a self-contained, achievable task for
users who are new with PyQGIS programming. You can teach this without
having to go into depth about plugin infrastructure/standalone
scripts/etc and instead concentrate on the basics of using the QGIS
python bindings. It's a good way for users to quickly gain confidence
in starting out with PyQGIS.
