I'm curious as to this trend as well. I've read the justifications for it in each case and in this particular one I don't get it. Isn't Flow more concerned with soundness than intellisense? Has TypeScript caught up with Flow in this regard? Perhaps it's because I prefer to do my work in strongly typed, pure FP languages where I can but I work professionally with JS and have been investing in Flow there for over a year now. While Flow is still not exactly great it can at least mimic exhaustive pattern matching and catches most unsafe type errors without getting in the way of common JS patterns too much. The reason the yarn maintainers are giving is because they want more contributors? What advantage will that have if TypeScript isn't catching the errors you used to be able to catch or don't know about yet? Curious to know if it's worth migrating over to TS without sacrificing anything other than the minor inconvenience.
