Research direction
Start with azure-pipelines-gitTests.yml, the linked pipeline logs, and the listed repository outcomes to compare TypeScript 5.5.0-dev.20240414 with 5.4.5. Trace each reported error to the affected repository and determine whether it is an intentional option removal, a project error, or a compiler regression. Done means the relevant causes are confirmed and connected to the appropriate follow-up issue.
