// Intentions have different namespacing to the rest of the UI in that the don't
// have a Namespace property, the DestinationNS is essentially its namespace.
// Listing of intentions still requires the `ns` query string parameter which
// will give us all the intentions that have the `ns` as either the SourceNS or
// the DestinationNS.

// TODO: Investigate the above to see if we should only list intentions with
// Source/Destination in the currently selected nspace or leave as is.
