Given infinite time, you are right of course.
For the open source projects where I’m maintainer, I’m already happy if I get “just” feedback.
As far as Darktable is concerned, I am currently involved in improving the support for Olympus/OM cameras: Working with modules from Lua scripts in darktable - #227 by alpinist I will publish a recipe when done, and perhaps some of this can be even added to Darktable proper.
There seems to be a lot of attention for AgX already. My limited time is probably best used to improve areas that not enough people seem to care about, like the above problem where images from OM-D cameras show a weird dark band when processed in Darktable.
