Hey, donluca here, looks like you've found my pet project, running Debian on PSClassic :)

Conky is a necessary evil because there's no swap and space is limited so, especially for the RAM limit, you must always have an eye open on RAM usage on Conky to make sure you don't go over the limit or you'll have to reboot because apps will close, stuff will end being messed up, etc.

As for LXQt... I wanted to give a newbie friendly environment for people testing this out and having a complete desktop environment is great.

If I had to do this for power users, I'd just use Alpine Linux with Wayland and Weston so we (kind of) have GPU hardware acceleration as well.
