libadwaita is the best thing happened in the Linux ecosystem.
pamac was always being designed as a Gnome app and always follows the latest design concepts - period.
Reading such things and in such tone from the main dev of Manjaro is truly disturbing. Neglecting KDE and making it look horrible with that libadwaita/GTK4 -whichever it is- abomination by not providing an alternative, native pamac version based on Qt is in my opinion a reason for “Dropping Manjaro from the 1st page of distributions with KDE” 2.0 . (1.0 was in October 2021).
