Hey @jakebailey, 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/155726/artifacts?artifactName=tgz&fileId=A69E37B9212D62DCD67B1D2B07773EE71184B62F0341BD915A86B2842E31D65B02&fileName=/typescript-5.2.0-insiders.20230628.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@5.2.0-pr-54777-9".;

Generally speaking I think I probably need to have @RyanCavanaugh / @DanielRosenwasser give the resulting setup a once over to make sure it lines up with their mental models; I think it matches Ryan's comment in the linked issue, but I'm also a little unsure that I like the end result either.
