Compare API dox of Q_DECLARE_METATYPE:
"
Some types are registered automatically and do not need this macro:
* Pointers to classes derived from QObject
* QPointer<T>, QSharedPointer<T>, QWeakPointer<T>,
where T is a class that derives from QObject
"
This is a ABI-compatible change, as this just replaces explicitly
defined template code (by the Q_DECLARE_METATYPE macro use) with the
generic predefined one picking up pointers to QObject subclasses.
So instead of the custom explicitly template overload
template <>
struct QMetaTypeId< TYPE >
{ /**/ static int qt_metatype_id() {/**/} };
the predefined template overload one is picked up via
template <typename T>
struct QMetaTypeId : public QMetaTypeIdQObject<T>
{ /**/ };
template <typename T, int =
QtPrivate::IsPointerToTypeDerivedFromQObject<T>::Value ?
QMetaType::PointerToQObject :
/**/ 0>
struct QMetaTypeIdQObject
{ /**/ };
template <typename T>
struct QMetaTypeIdQObject<T*, QMetaType::PointerToQObject>
{ /**/ static int qt_metatype_id() {/**/} };
And thus the constexpr code using QMetaTypeId<T>::qt_metatype_id(),
for which all this is done, evaluates as before.

Plasma Framework
Foundational libraries, components, and tools of the Plasma workspaces
Introduction
The plasma framework provides the following:
- QML components
- A C++ library: libplasma
- Script engines
QML components
org.kde.plasma.core
Bindings for libplasma functionality, such as DataEngine and FrameSvg, see @ref core.
org.kde.plasma.components
Graphical components for common items such as buttons, lineedits, tabbars and so on. Compatible subset of the MeeGo components used on the N9, see @ref plasmacomponents.
org.kde.plasma.extras
Extra graphical components that extend org.kde.plasma.components but are not in the standard api, see @ref plasmaextracomponents.
org.kde.plasma.plasmoid
Attached properties for manipulating the current applet or containment, see @ref libplasmaquick
libplasma
This C++ library provides:
- rendering of SVG themes
- loading of files from a certain filesystem structure: packages
- data access through data engines
- loading of the plugin structure of the workspace: containments and applets
See @ref libplasma.
Script engines
Provides support to create applets or containments in various scripting languages.
