There is no expectation or obligation to ever become more. It is just for fun, learning, and curiousity. I can add whatever features I want. I can use whatever technologies I want. I can throw it all away if I want. These are the projects I yearn for and look forward to when I'm busy with work.
Perhaps George Bernard Shaw was on to something: "We don't stop playing because we grow old; we grow old because we stop playing."
Funny enough, Titus Barik published a paper that contributes a qualitative analysis on the sentiment of programming and play on Hacker News.

Whatever you do, don't forget Bob Dylan's wise words about the things you enjoy doing: "you're gonna have to serve somebody".
