overall I am not against changes for 1.1.x, on our master branch. Here is something that Sebi mentioned a few month ago: https://issues.jboss.org/browse/AGPUSH-534
With some API change, coming up, let's not forget about "REST API Versioning", he discussed at our Face2Face meeting: http://oksoclap.com/p/jbrS1EHWkI(looks like in that session the majority preferred headers over URI).We have to support the 1.0.0 APIs for quite a while.
