When introducing QRangeModel for Qt 6.10 I wrote that we'd try to tackle some limitations in future releases. In Qt 611, QRangeModel supports caching ranges like std::views::filter, and provides a customization point for reading from and writing role-data to items that are not gadgets, objects, or associative containers. The two biggest additions make it possible to safely operate on the underlying model data and structure without using QAbstractItemModel API.
