Another thought .. why not use a plugin (which could emulate geometry component of DLT provider) to add geometry virtual fields to an existing layer? Sounds really straightforward and would be available immediately and on older versions of QGIS.

Extending the CSV provider would result in rewriting a lot of driver code which is already present in OGR. I'd rather use one of the two methods * Geometry generators * Virtual layer To build this functionality on top of any existing provider.
