if qt6.5 has proved its value,this can be considered.

6.5.1 will release 23-05, I hope it will be stable version of QT.

I think we have to keep qmake/qt5 support until the release of KDE 6.

Not having the KDE's theme is too shocking for Linux users, especially the "stable distro" users.

(However, this is considered as progression by rolling distros fans like arch/gentoo 😅)
