> finally installs C that depends on X.
> When A is removed, then Z is clearly not needed anymore. This is easy to
> figure out in this simple example, but when ~200 SBo packages are installed
> in the system it's not straightforward.
> Is there any tool for automatic detection of such "orphaned" dependencies
> that can be safely removed?

I use the attached shell script that I run every so often.  It uses
the sbopkg repo, so you will need sbopkg installed and updated.

The left column is the name of parent packages, and the right column
is everything missing from REQUIRES in the .info file.
