Whether they're formally deprecated is a separate question. We've
seen that lots of developers don't like us to deprecate things that
work perfectly well. We may just want to steer people towards a
different approach using CDI while leaving the existing APIs unchanged.

I don't think we're planning to subset CDI. The decision to be made
is whether the dependency on CDI is hard or soft. If soft, JAX-RS would
work without CDI, but some things might have to be done in a less
convenient way.

Are there objects that can only be acquired using injection, and can't
be acquired any other way?
