Seeing a project on a pretty high major is a positive signal to me. It tells me that they understand semver and know how to use breaking changes. Of course if a project is just very stable and sticks to 1.x, that‘s great too. I don‘t consider that a negative signal. Purely anecdotally, 3 is the scariest version number to me.
React sets a pretty good example here: react 17 is the most boring release in the world. The react team are not bad API designers that made 17 major mistakes. They may be the most considerate and pleasant API designers in all of frontend, actually.
React Native is on 0.64.4 (?) not because it‘s unfit for production but because they know the level of guarantees they can make about version upgrades is zero.
