-------------------------------------------------------------

CDI is opt-out by default, which breaks transitive reuse of CDI jars.

Presume this reuse scenario:

seam-solder has solderBeans.xml
seam-security depends on seam-solder and has securityBeans.xml
guvnor depends on seam-security (but not directly on seam-solder) and has guvnorBeans.xml. Transitively, seam-solder appears in the classpath.

So when guvnorBeans.xml does:
  <weld:scan><weld:include>securityBeans.xml</weld:include></weld:scan>
it fails, because solderBeans.xml isn't activated,
because securityBeans.xml doesn't define it's dependent beans.xml explicitly.
The hack of specifying to include solderBeans.xml in guvnorBeans.xml, is bad:
- guvnor doesn't want to know about solder. It's transitive: let seam-security take the heat for it.
- the next version of seam-security might no longer use solderBeans.xml (or instead need extra Beans.xml) => upgrading becomes hard


Possible solution: a beans.xml file should explicitly define its beans.xml dependencies.
