I think cheese was not starting at all if there were no effects
installed. I quickly tested again now and cheese seems to be OK if the
gnome-video-effects package is not installed. So we could lower the
dependency to a recommends.
BUT that will not solve the problem at all as cheese itself needs the
camerabin plugin from gstreamer1.0-plugins-bad (libcheese8 depends on
it). libcheese8 is used by cheese but also gnome-control-center,
gnome-contacts, gnome-initial-setup (and also indirectly by empathy). I
personally don't want to disable cheese support in all these components.
gstreamer1.0-plugins-bad is actually containing other plugins that looks
useful to me (or might be useful in the future like the waylandsink) and
not only "codecs for playing Nintendo games".
In ubuntu they are splitting more the package (same for the
gnome-video-effects package actually) and are also moving at build time
some of the plugins to gstreamer1.0-plugins-good. Following what ubuntu
is doing might be an idea but it will require more work from the
gstreamer maintainer I guess (I'm adding them in the loop) and we might
be a bit late in the development cycle to do that now.
