+I (Andrew Belt) generally do not accept unpaid contributions to the Rack codebase itself due to time costs.
 
 Writing code is easy. Instead, the difficulty of changing Rack's source code involves
+
 - research to devise the best solution with a convincing argument
 - acceptance of API/ABI change proposals
+- generalizability to solve similar issues, and flexibility for solving future solutions without an entire rewrite
+- future-proofing to avoid unnecessarily breaking patches or API/ABI in the near future
 - testing on relevant platforms, hardware devices, plugins, etc.
 - dedication to maintain the code in the future
-- generalizability to solve similar issues, and flexibility for solving future solutions without an entire rewrite
 - sometimes legal review
 
-Unpaid contributions typically omit many of the above tasks, making the code more expensive for me to accept than if I had written it myself.

 - Dependencies of Rack. Especially [nanovg](https://github.com/memononen/nanovg)'s performance, [rtaudio](https://github.com/thestk/rtaudio)/[rtmidi](https://github.com/thestk/rtmidi)'s stability and compatibility, and maybe even touch support in [GLFW](https://github.com/glfw/glfw). You would be helping many more projects than just Rack.
