I don’t follow how it would be in Anthropic’s interests to maintain an LTS version of Bun. It seems unlikely they’d use it, and it would cost them money (in the form of labor).

To my understanding, Java and .NET offer public LTSes because they’re financially buoyed by huge companies using those LTS versions, and Oracle and Microsoft are fundamentally selling that LTS support as a product. I have no idea why Node does, maybe it’s similar. But Bun’s position appears to be different than all three.
