This is a very safe fix. If possible, we should cherry pick it for 4.3.

Hey @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/103786/artifacts?artifactName=tgz&fileId=2CB484CD98847912C74630D9090A4ACD9170A4BE670BCDC20897A5466355A81402&fileName=/typescript-4.4.0-insiders.20210524.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-44219-7".;

@ahejlsberg the Node 10 check time numbers have me a little bit concerned. Any idea what could have caused that?

Those deltas are all in the noise. If you don't like them, just run the tests again. 😉
