Oh yes, I forgot to mention another goal is to enable `cargo-semver-checks` after v1.0.0.

We currently have an [`oxc`](https://docs.rs/oxc/0.24.2/oxc/) crate for unifying all the sub-crates. I plan to expose a `Compiler` API similar to `rustc_driver` and `rustc_interface`. The [rustc API](https://doc.rust-lang.org/nightly/nightly-rustc/rustc_driver/struct.RunCompiler.html) uses callbacks, closures and...

I decided to not include any builder patterns in the public APIs, they are super confusing for new comers from JavaScript, who are used to passing objects with spread `{...

It seems like we need a `TransformerFactory` for storing options, otherwise we'll be repeatedly initializing the options. But ... I'll just add `define` and `inject` options to `TransformOptions` to get...
