The branch name is "claude/phase-a-port", there was zero indication this was an experiment until Jarred commented. The more accurate title might have simply been "there is a branch in the official repo of bun describing a port to rust from zig". No amount of soft titles would have prevented the discussion. People have their opinions about Bun, about Zig, about Rust and it's all going to come out in a discussion board.

  The goal of Phase A is a **draft** `.rs` next to the `.zig`
  that captures the logic faithfully — it does **not** need to compile. Phase B
  makes it compile crate-by-crate.

I couldn't use that title because I didn't know if it an experiment at the moment. Even now the correct title would be "Bun author says that he is entertaining the idea of porting it from Zig to Rust, creates an experimental branch".
