Mind making this a configurable option as well? Effectively aligning with Rust's --format option for wit-bindgen rust

Sure. It looks like formatting is disabled by default for Rust. Any particular reason for that vs. enabling it by default and providing a --no-format option instead?

I personally prefer "positive" options along the lines of --format and --format=no vs --no-format since I find negatives/double-negatives hard to understand.

Clap supports --foo[=true|false] which means this flag can be --format, on-by-default, and disabled with --format=false, which I think is fine.

Makes sense, but am I correct that it's off-by-default for Rust? Should we turn it on by default there to match what I'll be doing for Go?

You're right yeah it's off-by-default, but for now I think it's ok for different generators to differ on defaults. I think it's fine to leave it disabled-by-default in Rust since generated code is handled differently than the Go side of things.
