"all"? There's loads of them for all sorts of subsystems, so feel free
to take it through your subsystem tree if you want. I usually scoop up
the ones that no one picks after a release and take them through my
tree, to pick up the stragglers.
So it's your call, whatever is easier for you is fine for me.
