Longer term, do you think it would be possible to rewrite the other modules with it? Would it be possible to ditch jackson where it's already used and use GSON instead, or in other words, does GSON have a low level API to build JSON? Does it have anything higher level like jackson-databind? What about the opposite (do everything that's done with gson using jackson instead?). Both libraries are well maintained and their core version is small enough, jackson at 300k, gson at 230kb.
