Now that LXQt is a thing, is LXDE officially abandoned as a desktop environment? I personally like GTK more than Qt, and LXDE is also lighter on resources, especially since most Linux apps are GTK, which LXQt would have to use memory to load the libraries for. Is there any chance that LXDE could continue to get support? Otherwise, how likely is it that it would be forked and continue to be developed for like Unity was?

Failing all those, are there any actively developed desktop environments that use GTK and are as lightweight as LXDE?
