Hello Gili,
Trying to get the community organized and involved in contributing improvements to Guice and Spring support in HK2 and Jersey 2 is the right step. Please feel free to contribute any new features and/or improvements to current support.
Cheers,
Marek
P.S. As much as I understand why people using Spring and Guice are upset about this, I still do not think it was a mistake to release Jersey 2 without a Spring and Guice support. Jersey now provides JSR-330 injection (via HK2) without any need for Spring or Guice. Also, support for Spring and Guice was not the primary release or feature driver for Jersey. JAX-RS 2.0 support and releasing JAX-RS 2.0 RI was the primary motivation for the earliest possible release.

I think it was a mistake to release Jersey 2.0 without first testing Guice and Spring support. Spring support was added a few months after the initial release and it still suffers from some pretty serious limitations (inability to inject beans into JAX-RS classes using XML configuration). Guice support is still dead in the water.
