Faces 4.0: WELD-001408: Unsatisfied dependencies for Push & FlowBuilderParameter

FacesArtifactProducer is only registered when @FacesConfig is present.  This means @Push and @FlowBuilderParameter are used, Weld will report these errors:

WELD-001408: Unsatisfied dependencies for type FlowBuilder with qualifiers @FlowBuilderParameter
WELD-001408: Unsatisfied dependencies for type PushContext with qualifiers @Push

This breaks many applications, as what previously worked does not.

Just for reference: PushContextFactoryBean.java was previously used for the cdi producer registration, but was removed.  The getPushContext method was moved to the FacesArtifactProducer (JsfArtifactProducer).

https://github.com/apache/myfaces/commit/6f5599a219ae1f19d6a6ba7a8a9dc566b0bff1a4#diff-1184a79edde14f5fcedfb0b2dde1f8e89cb5c259b1f7c3980036ebb4d5bf7d1dL37-L40

I think the solution is to have Faces behave as if @FacesConfig is present (even when it's not).  In other words, always register cdi producers.
