In red-pill mode, you get to see the "magic:sys" package.  Updating it
does some kind of "Update All".

That would really help since you can still get the new cairo without
the new radio applet.  Even if you lock cairo and the radio applet
together via their own dependencies, you would get the effect of the
meta package, but in more messy and non-scalable way.  If you want to
lock them together, doing it with the meta package should be cleaner.
