It's frustrating that innovators are constantly having to justify "why yet another". Folks should just be able to freely innovate without fear of getting spammed with xkcd#927. You wanna make yet another programming language, compiler, JSON-alternative, container format, or trivial FTP+SVN killer, go for it! This is how we innovate.
As others have pointed out, there's a difference between creating something just for the experience of it, and creating something because no other similar solutions exist. This project seems to fit in the latter category hence why a justification has been offered.
