Very correct Husky.
It did resurface in odd topics.
The discussion is not about UCS vs WCS or a 'Move/Rotate/Scale All' tool.
Here, initially this topic was about that Qcad did not save a certain ZERO.
Remark that the file with such a ZERO is still out.
I doubt that it will be UCSORG and UCSXDIR as they are AC system vars.
A good functional USC has its use and may even solve things we can't do upright.
Like moving and slanting the piece of paper you write on.
