Semver has a really odd relationship with software maturity. I'd take a v0.21 project over a v1.0 project.

For hobby projects, I really like software where I can do small features or tweaks. Sometimes I don't have time for anything more substantial. Website projects are great for this. Are there other areas?

It feels like a mature software project is one where bugs require multiple commits to fix. You've hammered out the basic issues, so the remaining issues are often weird interactions between components.
