Qt for Python (PySide/Shiboken)

I'm getting ImportError: cannot import name 'QModelRoleDataSpan' from 'PySide6.QtCore' when running under PySide 6.7. According to the C++ documentation, QModelRoleDataSpan should be available since Qt 6.0. But it somehow isn't there? Since the documentation for 6.7 was pruned, I can't verify if it was missing from older PySide. Do I need to increase the minimum version required to 6.8?
