This also seems like a lot of work to do just to enable/disable one feature, but I guess if there’s no framework for enabling/disabling JS features in JSC at all then it’s necessary.

I’m sad that the V8 code generator script diverged so much from the original. It would be great if they were kept closer. I have refactored them to become more similar and even share code whenever I had to modify both, such as when making changes to [Reflect].

I think it would probably be good. Not sure why the person who did it originally did it V8-only.
