My proposal is suitable for this project

• I believe my proposal would be useful to the broader TypeScript community (meaning it is not a niche proposal).

Description

Back in #7834, we noted that the getTypeArguments function in type-utils is no longer necessary. It wrapped around a checker.getTypeArguments function added in TypeScript 3.7... which is well below the minimum version of TypeScript we support! The only reason we didn't delete the getTypeArguments function was that it would be a breaking change for API consumers.

But, we're working on a v8 major version - now's the time to delete the unnecessary code! 🔪

Additional Info

Note that the PR to delete this should be targeted against the v8 branch.
