What's a standard OSGi service?

I wouldn't promote or limit anything.
It should be all POJO at the end, with some entry-point on what the AS7 should trigger when deployment is fully deployed.
That's what BundleActivator is in OSGi land, BeanManager in Weld, Injector in Guice, ...
Imho CDI / JSR-330 should be the default (and I think that's already the case),
while anything custom can be easily hacked up with annotations, marking what's a service and what's not.

Old / existing services (e.g. Tx), can easily be added via Provider / Produces pattern.
