I won't speak for anyone else but sometimes "bugs" in more about process than code. I have a similar project as the GP and am not currently interested in open sourcing the project because there's a lot of bespoke elements and manual setup process. I don't want to have to make a README describing all the process steps that make my code actually useful.

For me, on my hardware, on my network, I've got a process that works. It's a non-zero amount of effort to generalize the description of that process.
