For the record QGIS has comprehensive curved geometry support,
including dozens of editing tools for creating and manipulating curved
geometries. Again, we see a lot of demand for these from European
users who need to work with official mandated data models.

I would **love** to see curved geometry support land in GEOS in the
future so that we can migrate a lot of downstream logic up to GEOS
(where it arguably belongs).
