20 days post-Claude Code leak: Did the accidental "open sourcing" actually matter for local devs?

Now that its been about 20 days since Claude code source code got leaked, what really came out of it? Sure, we learned some of the inside tricks they use, we understood how much of it is vibecoded, many forks were made. But did it help in any way? Out of the forks made, I don't even know if any of them work reliably well enough to pay attention to. Did any of the pre-existing popular harnesses actually adopt their parallel tool-calling logic or diffing techniques? I would love to know how if this leaked peeling back the curtain on their orchestration helped anyone here.
