The goal of Lucia v3 was to be the easiest and cleanest way to implement database-backed sessions in your projects. It didn't have to be a library. I just assumed that a library will be the answer. But I ultimately came to conclusion that my assumption was wrong. I don't see this change as me abandoning the project. In fact, I think it's a step forward. If implementing sessions wasn't easy, I wouldn't be deprecating the package. But why wouldn't a library be the answer? It seems like a such an obvious answer. One word - database. I talked about how database adapters were a significant complexity tax to the library. I think a lot of people interpreted that as maintenance burden on myself. That's not wrong, but the bigger issue is how the adapters limit the API. Adapters always felt like a black box to me as both an end user and a maintainer. It's very hard to design something clean around it and makes everything clunky and fragile, especially when you need to deal with TypeScript shenanigans.

But I believe the core philosophy of tiny modules is actually sound and easier to maintain than giant frameworks.
