> I am a little worried that this will change the output structure of
`printTopology`. I wonder if this will be an incompatible change. Do I need to
add a releaseNote? @tasanuma @virajjasani Could you please give some
suggestions? Thanks.
@tomscut sounds good, we can keep this to trunk and add release note as well
reg the output format change, thanks!

> of these nodes are alive, DECOMMISSIONED, or DECOMMISSION_INPROGRESS. It
