Today, the DOM types are auto-deployed to npm, but the story there is extremely confusing. If breaks are introduced in a newer version of TypeScript, we can tell users to lock down their DOM types with @types/web, but there's no easy way to tell which version of @types/web corresponds to a specific version of TypeScript.

We need to come up with some stable scheme where

• TypeScript's (stable) publishing process has a corresponding release (or tag for an existing release) for @types/web.
• a tag should be relatively easy to identify - something like npm install @types/web@ts-4.9
• The tagging mechanism should also correspond to that of @types packages from DefinitelyTyped.
