When a SmithyBuilder implementation is missing a required property, the name of the class that was missing the property will be included in the error message. This is derived by looking at the stacktrace on error, so it's an inference. But even an inference of the builder class is better than having no idea which builder encountered an error when the stack trace of the IllegalStateException is elided for whatever reason.

There is a specific code path in SmithyBuild that results in impossible to debug error messages. It's caused when importing a model fails and results in a Model not being created at all (for example, this can happen if something really bad happens like a trait throwing a SourceException when calling toNode). In this case, SmithyBuild tries to create a ProjectionResult with no Model, but ProjectionResult requires a model. This is now detected, an empty model is provided, and the build will fail in a way that shows a proper error message.
