The TSF documentation is definitely sparse and there are some real challenges in getting up to speed with what is a very complex API. But the real challenges in input method implementation come more from the vast array of interpretations of how keyboard input should be consumed by Windows apps, and the extremely patchy support for TSF (and "foreign" language input) in apps. That's where I've killed thousands of hours over the last 15 years; once you get your head around the TSF model it's not too hard to code to. Clearly, you've seen some of the same compatibility problems with KMFL. And our experiences on Mac OS X, Android and iOS are much the same. For example, Norbert Lindenberg's excellent blog on developing keyboards for iOS details much that is missing from the API docs: http://norbertlindenberg.com/2014/12/developing-keyboards-for-ios/ There is a massive cost to developing -- and maintaining -- a native code input method for each language and each OS. I'm really trying to minimize this cost with Keyman Developer 9. Keyman Developer 9 is a free product (http://keyman.com/developer/). It is currently in beta but is relatively stable.
