Drupal 8 with Oracle Database

We are building a Drupal 8 site for a government agency and use Oracle. Is anyone using Oracle as the database for Drupal 8? I would like to know if the Drupal 8 Oracle Driver is stable or if we should avoid this configuration. 

I saw that this project was a development version which makes me concerned that there will be a lot of issues.
