Not sure there is anything official, but I just uncovered this sentiment in my research after scouring tons of chat forums, etc. while researching GUI toolkits. There seems to be an understanding that QtWidgets is in "maintenance mode" and I'm told hasn't seen any new features in a while. I've also noticed many existing projects discussing migrating to QML (many don't, however, due to the amount of work).

Did you even read the article? They literally just announced new features for Widgets, in the section titled "Useful new features in Qt Widgets".
