Additionally there are only three major memory hogs in KDE:
Akonadi, purely associated with the KDEPim stuff. You can just uninstall it all without a fuss.
Baloo, the file scanner. You can disable this outright.
Plasmashell, which is the desktop applet engine. This is where I feel LXQT can find its niche, by providing a simpler shell that uses less resources than the plasmoid JS script container style the Plasma Shell uses.
Without any of these running a KDE desktop with system services etc included is under 200MB, often under 100MB.
Honestly this entire post is a really good call, I didn't even realize whether or not I need all these. Is there a simple wiki or something out there that would help decide what can be disabled?
