-(define-public imagemagick
+;; This is a variant of the 'imagemagick' package that is not updated often.
+;; It is intended to be used as a native-input at build-time only, e.g. by
+;; 'gtk-doc' (via 'dblatex') for generating package documentation. This
+;; allows the main 'imagemagick' package to be freely updated on the 'master'
+;; branch without triggering an excessive number of rebuilds.
+;;
+;; Normally the grafts mechanism would be used, but there are often
+;; difficulties grafting imagemagick, e.g. because upstream changes the ABI
+;; between micro version updates. Also, the overwhelming majority of
+;; dependencies on imagemagick are via 'gtk-doc' in 'native-inputs', where
+;; grafting is ineffective. See:
+;; <https://lists.gnu.org/archive/html/guix-devel/2021-03/msg00381.html>.
