These two are done whenever GTK is in the transitive inputs of the
packages installed in the profile.

These two are done whenever GLib is in the transitive inputs of the
packages installed in the profile.

Both GTK and GLib are in the (direct) inputs of QEMU.

Even if you removed QEMU, GLib is also in the transitive inputs of Guix
itself, via the dependency path Guix -> Graphviz -> GTS -> GLib.

There's probably room for improvement here, but it's not entirely clear
how to make an optimal decision about when these profile hooks are
needed.
