IIRC, I won't read the thread again, all the mentioned WMs and DEs have a past and most likely a future. You might have noticed another thread, "plasma 5 crashing". The bloated DEs, especially GNOME and KDE do not provide a steady work-flow. New major releases often are released before they are stable, but again, even if those releases would be stable, the way they work changes and breaks the work-flow. I don't know if a version of LXDE still will be based on GTK in the future or if they will completely switch to Qt, the Internet might inform about this. You shouldn't worry about the future, you should care about your needs regarding configuration files, the work-flow, how the DE interacts with your computer usage. It perhaps wouldn't be smart to chose a 3D DE, if your install is based on linux-rt.
