[Cin]Not merged yet ffmpeg filters

I was looking for opencl lut3d filter (i think mpv uses lcms2 + opengl to drive its color-managed output) And there was patch, since last year, but it not yet merged https://ffmpeg.org/pipermail/ffmpeg-devel/2025-June/346001.html also there was inverse tonemapping (SDR to HDR) filter, slo not merged yet https://ffmpeg.org/pipermail/ffmpeg-devel/2025-July/346244.html but I think patch was incomplete? It modifies file that does not exist yet (may be it used normal tonmapping filter sources as renamed base and then added on that?)
