Please, let me know if Guix shows revert dependencies of installed packages?

I had the same issue, but with qtwebkit. Maybe this could help:

--8<---------------cut here---------------start------------->8---

for i in $(guix package -I | awk '{print $1}') ; do guix graph $i | grep -q qtwebkit && echo $i ; done

--8<---------------cut here---------------end--------------->8---
