Yes, that's the answer.
From the Developer's Guide:
[The Policy Injection Application Block] is provided mainly for backwards compatibility with existing applications.
In version 5.0 of Enterprise Library, the recommended approach for implementing policy injection is through the Unity interception mechanism. This supports several different techniques for implementing interception, including the creation of derived
classes rather than remoting proxies, and it has much less impact on application performance.
