#CrabLang (a fork of #Rust), reminds me of Io.js, which forked from #Node.js because corporate sponsors were holding the language back. Due to extreme bureaucratic caution, adding new JavaScript features to Node.js took a very long time (years!).

The good thing is that this led to the formation of the Node.js Foundation and, eventually, the #OpenJS Foundation. The result is a platform with better governance and faster iteration. #Io.js and #Node.js were merged in the end.
