Hey Daniel Rosenwasser (@DanielRosenwasser), I've packed this into an installable tgz. You can install it for testing by referencing it in your package.json like so:

{
    "devDependencies": {
        "typescript": "https://typescript.visualstudio.com/cf7ac146-d525-443c-b23c-0d58337efebc/_apis/build/builds/106775/artifacts?artifactName=tgz&fileId=63B93A602411BFF1CDB57AA1BA24CA322AB0A53CC5F3365126AFBC0C64BD9CEC02&fileName=/typescript-4.4.0-insiders.20210714.tgz"
    }
}

and then running npm install.

There is also a playground for this build and an npm module you can use via "typescript": "npm:@typescript-deploys/pr-build@4.4.0-pr-45007-6".;

I think this is fine, but I'd rather hold off on it for TypeScript 4.5.

This does look fine - Ron Buckton (@rbuckton) might wanna review the impact on generator IIFEs, since I think we may have talked about something similar back when we updated the generator types.
