In GDAL 3.12, OGRFeature::GetDefnRef now returns a const pointer.
This means that calling Reference() or Dereference() is no longer
possible. Does this mean that this is now automatic?
No. The ref count is modified when creating / destroying the layer
(when it is linked to a layer), or when creating / destroying features
using it.
What would be the use case for manually incrementing/decrementing the
ref count of a OGRFeatureDefn* returned by OGRFeature::GetDefnRef() ?
Encapsulating the object into a wrapper when returning the object to a
language with automatic GC.
If I don't do this, I will have to keep a reference to the layer or the
feature. Or clone it.
