Jaak,

There's no driver metadata that can tell you if update is supported or not by 
just calling TestCapabability() at the driver level.

If you have an existing datasource, you can for example test the 
OLCRandomWrite capability at the layer level.

But if I understand well your need is not to have a list that would be 
generated dynamically but rather pick up a format that support update ? If so, 
SQLite / Spatialite should be a good choice .
