Reporting only leaf packages was a limitation, not a goal.  The
limitation stemmed from the fact that, to determine whether a package is
vulnerable, we need to (1) map its store file name to its package name,
and (2) map its package name to its CPE name.

We can do #1 via manifests, but only for leaf packages (because there’s
no metadata available for other store items).

I’m all for composition, who wouldn’t?  :-)

I think composition works best within a rich language; sending text over
pipes is often too limited.

There’s been progress since I posted this patch: manifests now include
provenance info, which means we can map profiles back to package
definitions!  So we could make a proper ‘guix health’ at this stage.

I’d like to say I’ll work on it soon but reality is that I’m a bit
swamped.  Anyhow, I think it remains a useful tool, and whether it’s me
or someone else working on it, we should probably aim for it at some
point.

Thanks,
Ludo’.
