Sounds good to me.

At a future time maybe all currently terminating actions could be
reviewed and possibly be turned into SetXxxAction (ex SetPoolAction)
which then would imply "Continue". Personally I like the iptables design
where there are only very few terminating actions ("targets" in
iptables lingo), and almost everything else implicitly continues.
Writing this in a very vague way as I haven't even done a
preliminary analysis what this would entail...
