On the other hand, though - creating this dependency *will* break workflows
and cause many unexpected side-effects, as it broke mine last month: I have
linux-headers-cloud-amd64 installed; when this package hit BPO, it brought
in linux-image-cloud-amd64, which grub then tracked as the most recent
kernel and booted into, causing (ironically) many drivers to be missing and
the system failed to boot correctly as a result (it is not a cloud server,
but it does build modules *for* cloud servers). It also brought my /boot to
98% full, fortunately this did not cause problems by itself, but obviously
came close to doing so.

It has been consistently asserted that installing superfluous image files
is harmless; I want to point out that this is anything but true, even aside
from the more philosophical issues around having "source" packages depend
on "binary" ones, and the precise meaning of "significant functionality" in
the Debian policy.
