Hello, Guix Help! Updating with `guix pull` and `guix package -u` has made me waiting for 3 hours already. webkitgtk is compiling so long.

I've checked all browsers I have and found this is epiphany that needs webkitgtk

$ guix package --show=epiphany | grep gtk
+ gnome-desktop@3.24.2 gsettings-desktop-schemas@3.24.1 gtk+@3.24.0
+ sqlite@3.24.0 webkitgtk@2.22.4

But I have not found in manual revert dependencies graph.

Does Guix can show revert dependencies? I want only type something to check what the package needs webkitgtk.

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