It would be great if it was possible to develop a plugin for an engine to load spine in a game and let the decision of the license to the game developer (and not the engine developer). Right now you either are blessed that the spine devs decided to care for your engine or you aren't. It would be nice if a FOSS engine dev could develop a Spine plugin and then a game dev that was thinking about that engine could either opt to use it or not.
