Perhaps he is doing all of this work with the wrong goal in mind. If you start out building something for other people, you're always going to gamble that other people may not need it.

But if you're building tools for yourself, and documenting for yourself, because you have an actual need for these things, then regardless of what others do with them, you'll be happy because you have tools that make your life easier.

Do the bare minimum for yourself that makes your life easier. If other people want to use it, then start building from there. But don't kill yourself trying to build stuff you think will stroke your ego. Programming is probably the worst tool you could use to solve that problem ;)
