Calver side-steps this user bias.
Users shy away from major version numbers because they are allowed to change things in incompatible ways. When you jump a major version you're signaling that stuff might intentionally break, and they make their decisions accordingly. The solution is not to make your communication with user even worse!
I dislike the idea of going away from SemVer just for marketing purposes. At least as a user when I’m going to upgrade versions then I could see that “oh, this version doesn’t break compatibility”
Well, no, it just means users won't update at all, because every version could be breaking...
