(I'm going through old bug reports that unfortunately weren't resolved
at the time.)

That command removes packages that were not installed explicitly, but
were installed as a dependency for package(s) that you've later removed.

"Not used" is not the criterion.

Did that command remove anything that you hadn't installed explicitly?
I tested the command here, but it seems like it's working as designed
for me.

If you see a bug here, do you have a recipe to reproduce it, starting
from "emacs -Q"?
