🕗 Version & Regression Information
This is the behavior in every version I tried, and I reviewed the FAQ for entries about "jsx"

💻 Code
// @jsx: react
// @jsxFactory: element
// @jsxFragmentFactory: fragment
// @noUnusedLocals
// @filename: index.tsx
import {element, fragment} from './jsx';
console.log(<>Fragment</>);
// @filename: jsx.ts
export function element() {}
export function fragment() {} Workbench Repro
🙁 Actual behavior
'element' is declared but its value is never read.
🙂 Expected behavior
element is used in the generated output so should not be found as unused.
Generated output:
console.log(element(fragment, null, "Fragment"));
Additional information about the issue
Using pragmas instead of tsconfig works as expected so hopefully it's not a big gap to align these
