No, because if I have a library that is feature complete, this would force me to create a release per year, because people will think the library is outdated. One of my customers uses that to force his customers to update to the newest version.

I like CalVer whenever versions become a point of discussion; it's hard to argue to continue to use 2019.08 today, whereas 1.5 hides that nuance of using outdated technology. Breaking changes with SemVer are a solved problem when you use the right technology! ;)
