# kvantum-qt5 has to go in the same transaction: it is the only thing that

# been dead weight since VLC was retired anyway, and it takes qt5-svg and
# qt5-x11extras with it.
#
# What this deliberately does NOT touch is qt5-wayland and qt5-declarative. On a
# machine whose sddm theme metadata predates QtVersion=6, those are what keep
# the Qt5 greeter able to start, and removing them is how you end up with no
# login screen. qt5-wayland is explicitly installed, so the -s cascade leaves it
# and the qt5-base beneath it alone.
