React Native is 0.63 and is production ready for years
That’s definitely an outlier / exception to the rule … First of all, React Native is developed, financially backed, promoted and heavily used by massive companies. Secondly, there’s the great branding associated with React that React Native piggy backs on. Sure, React Native is not yet in 1.0, but React is and has been for a long time.
Follow-up / edit: My point is, by having a 0.x.y version, you’re already raising eyebrows for folks who may not be fully aware of the language / library / ecosystem. So it’s already an up-hill battle at that point.
