Over in DeltaSpike we are currently discussing the jpa module. Plans are to implement it there as portable extension. I see no need why we need to duplicate the effort by implementing it in both Weld and OWB ;)

The big benefit of this approach is that this will also run on any CDI-1.0 container!

LieGrue,

Otherwise there is not enough core services to provide a dependable and portable programming model. If you (general audience) want to use a Servlet container, you aren't using Java EE and will have to supplement with addons like CDI extensions or Spring.
