title: What is the downside of using third-party plugins in JIRA?
body: <p>We are considering using several third-party plugins (such as Structure) in JIRA.
  <br>Is it possible that after an upgrade of JIRA some of those third-party plugins will stop working? That would mean that our JIRA will become unusable, since those plugins are required for the workflow to function.
  <br>For example: 
  <br> - JIRA issues a security patch, and a third-party plugin is not
     compatible with the patched JIRA version;
  <br> - JIRA issues an update, and a third-party plugin is not compatible with the updated JIRA version.</p>
