You do these tools for yourself and to scratch your own itch. As long as it fulfills its function, you get value. The fact that someone else may want to use it or the big vendor would like to adopt it should be secondary at best.

If you yourself don’t need such a tool and you also don’t want to do it as an exercise of the art, then don’t do it. Spend your time on something that’s gonna bring value to you instead.
