Sometimes you don't have a choice. I have worked on a few frameworks that have gone defunct over the years. Cocos2D-Objective-C, Kindle Active Content, XNA, J2ME, Flash Actionscript to name a few. You have to port it to some other framework, and usually I ended up wanting to clean up a few things in the process (or in Kindle's case, I needed to, because it had so many constraints), or have to add new features for new expectations (480P->720P->1080P->1440P resolution, 2D->3D, add online multiplayer, streaming features, maybe the market shifted to expecting mobile apps to be free so now you need to rework the design, etc). When you're working on it in your spare time, sometimes those things happen before you get a chance to finish the project and get it out there.
