I'm waiting for a confirmation from RedHat that they agree with the proposed change.

As such, we are not going to make it simpler for anyone to do ugly stuff. One can use directly lower-level Servlet API if wants to do something non-RESTful with HTTP.

Isn't it already too late at that point (the stream is already flushed)? This also sounds like maintenance hell for unit tests! If you'd really like to punt to the lower-level Servlet API, there should be an (easy!) way for me to translate a Jersey request/response to a Servlet request/response within the same method (as opposed to using filters which require me to spread the logic across multiple classes). The resulting code has to be easy to maintain.

Are you expecting me to pass null into entity or MediaType in this method? https://jersey.java.net/apidocs/snapshot/jersey/javax/ws/rs/client/Entity.html#entity(T, javax.ws.rs.core.MediaType) If so, the Javadoc should really mention that passing null is an acceptable way to omit the field.
