Generally agree, we're targeting teams who need to make agents accessible to both their developers and non-developers in one platform. There's not really a way to do that as far as I know in any other framework. That said, I do find with multi-agent systems, having good abstraction layers makes things like observability, tracing, etc. cleaner. When the LLMs are driving the execution, normalizing on how the LLMs interact with each other can simplify the stack.
They are arguably "fun", it's kind of like functional programming but in NLP. We found multi-agent systems to work well for workflows where there's lots of unstructured inputs. E.g. a "content writer" that takes resolved support tickets and turns them into an update against documentation if there's something novel to update. We tried that with a structured workflow and it didn't work very well/reliably, while a multi-agent approach worked well. For more traditional mostly deterministic workflows, I agree, there's no need.
