  | Region.markNodeResident(Fqn, isResident);
  |   | Region.isNodeResident(Fqn);

Node metadata is the proper place to store this, since this flag would affect individual nodes, not regions of nodes.  Considering where we're going with node and region design, with Regions becoming a fully configurable top-level construct in future, I don't want to clutter up the Region API anyway.
