I've been replacing LangGraph with simple primitives, relying on native Python constructs, etc. For example, instead of building this verbose graph of computation with LangGraph, you can just...call functions in the order you want them. Or declare them async, add them to a list, then await the resolution of all of them.

For a time I was maintaining a spreadsheet of all the refactor PRs, and I had a cumulative reduction of over 1,000 lines of code from these changes. Eventually I stopped keeping track.

^ That's a 1K LOC reduction with no functionality changes. I feel pretty strongly that LangChain/LangGraph are a net negative for our use case.
