What did you check? Bun only has basic transpiring currently. I can't imagine what "everything" is, and without bundling, minification, and down-transpiling support I don't see how any meaningful project could have been tested on.

> Bun’s perf obsession has been percolating a lot of optimizations upstream to WebKit/JSC

Source? AFAIK claiming either "bun devs made a lot of JSC perf optimization PRs" or "bun devs pointed perf hot spots to JSC devs" would be incorrect, but I'd love to learn otherwise.

Yeah, build/bundling use cases have lagged in priority. I’ll rephrase “everything” as “every transpiling use case”.

Jarred’s Twitter has been frequently highlighting these contributions. This seems like a weird thing to object to if you’re so familiar with the project!

The highlighted contributions you're referring to are from day-to-day work by core JSC contributors/Apple employees.
