| <p>Che intends to use Kubernetes secrets as a storage for all sensitive user data. One namespace |
| per user simplifies the design of the workspaces. This is the reason why namespace strategies other than <code>per user</code> become |
| deprecated. The deprecation process happens in two steps. In the <code>First Step</code> namespace strategies other than <code>per user</code> are allowed but not recommended. In the <code>Second Step</code> support for namespace strategies other than <code>per user</code> is going to be removed.</p> |
