I have been using slackware with ion/notion WM for about two decades now and little has changed which is why I stick with it, I have no interest in having to relearn my system every update. In all these years I have only encountered one system change that caused me any grief, when they finally gave into PulseAudio I had some headaches but it was only an issue for me because I use my computer for music/recording and not really that big of an issue since Pulse had been out a good many years by that point and the solutions were easy to find.
