That's plus for individuals but minus for languages. Personal anecdote: I was exactly there a decade ago when I was working on Chrono, now one of best-known date and time libraries in Rust. Since I was simply my own, my design was not as good as it could have been. Of course it is still much better to have a suboptimal Chrono, but I can't deny that it remains and probably will remain suboptimal due to my design a decade ago.
