No, it'd be removed everywhere (thrift and zk path).  It'd basically
get rid of the notion of 'offline' shards - your usage is essentially
the same as the TopCommand I described. The trouble is that in a world
of random ports a lot of bookkeeping overhead would be necessary to
reliably maintain the notion of 'offline' or 'registered vs online'
shards.  As I understand it, the need for them was back when the
layout manager relied on that knowledge but the default layout manager
is more dynamic now.  Do you just display them or is there another
need in the console for them?
