I was just thinking about the sort of issues described in this post, like having to use specific flags to prevent the minifier breaking code, or write an extra pass to tweak the output. I’d worry about what other problems there might be that I hadn’t noticed yet.

Presumably those will get fixed over time, and at some point bun will just work if you want to replace your existing bundler. But even then, I personally would lean to sticking with esbuild as it’s more than fast enough for my purposes -- extra speed isn’t a compelling selling point (for me).
