You could use the mango-go logger - https://bitstep-ie.github.io/mango-go/latest/packages/logger/. It is built on top of slog and you can easily add attributes, and already has some config for checking mandatory attributes (fields).
We could work at extending that as for now it's fixed attributes that are required, so that we make it configurable etc... Any suggestions / use cases are welcome in the discussion forum.
