anchor.diff:  To disable service instance sharing, an administrator runs the following:
   
   <pre class="terminal">
  -	$ cf disable-feature-flag service_instance_sharing
  +$ cf disable-feature-flag service_instance_sharing
   </pre>
   
   This will only prevent new shares from being created. To remove existing shares, see [Deleting All Shares](#deleting).
  
positive.code: run <code>cf service SERVICE_INSTANCE</code> to see 
  how many bindings exist in the spaces the service instance is shared into.</p>
  
  You can unshare a service instance that has been shared from one space to another 
  if you have the SpaceDeveloper role in both spaces.
  You cannot delete or rename a service instance until it is unshared from all spaces.
  
  To unshare a service instance, run the following experimental cf CLI command:
  
  <pre class="terminal">
  $ cf v3-unshare-service SERVICE_INSTANCE -s OTHER_SPACE [-o OTHER_ORG] 
  </pre> 
  
  ## <a id="security"></a> Security Considerations
  
  
negative.code: 
  * Service instances can be shared into multiple spaces, across orgs.
  
  * Developers and administrators can share service instances between spaces
  in which they have the SpaceDeveloper role. 
  
  * Developers who have a service instance shared with them can only bind and unbind to that
