Does bun have a formal roadmap? I occasionally see some the changes that Jarred posts on X, and I wonder if they're really meaningful or not (perf improvements are always good). It also seems like a lot of the recent contributions are ai authored.

I tried using bun for a project earlier this year and learned that you can't use testcontainers(works fine w/ Deno).

I dont think so, but recent release includes a terminal markdown renderer built-in which means, even if handy, most of the focus is to make Claud Code great. I am not worried though, at least no yet.
