Most of the CAD software is Qt Based and I've been running an OpenBSD Dual 
Boot system with ArchLinux and LXQt.  Essentially, I tried to build the 
lightest, CAD compatible environment possible.  With all of Rafael Sadows' 
work, I suspect updating LXQt should be low hanging fruit.

My own build uses kwin instead of openbox and the only issue I had was turning 
off the animation eye candy without kwindowsystems installed.  It was actually 
a ~/config file that I preserved before deleting kwindowsystem.

The older meta-package brought in openbox and gtk dependencies that would be 
unused code when using kwin.  Kwin should also be more wayland friendly 
going forward.

I think it's worth opening a discussion to set the meta-package structure and 
get developers behind the project.  I'm not interested in spending days 
generating patches only to have them ignored for months and go stale.

If it can come together, I'll contribute some of the updates.
