I've tried to contribute to SDL a few times over the last couple of years as well. Never got a reply on any attempt whatsoever. Even getting a simple "rejected" label would've been nice. After Wayland support was added, I was trying to add support for running SDL apps inside the "fullscreen shell" style compositors (compositors meant to nest other compositors or run one application fullscreen).
