"How does this affect downstream tools"

> It’s worth calling out that workflows that use Vue, MDX, Astro, Svelte, and others will likely not yet be able to leverage TypeScript 7. Similarly, specialized type-checking within templates like Angular will also likely not use TypeScript 7. This is mainly because TypeScript 7 does not yet expose a stable programmatic API, and so tools (such as Volar) which embed TypeScript into their own compilers and language services can only currently rely on TypeScript 6.0. We expect this to be a point-in-time issue, as we are committed to providing a solution here. We will be actively working with the maintainers of these projects to ensure TypeScript 7 supports these workflows.
