💻 Code

let a: unknown;
let {foo} = a;
//   ^^^ Property 'foo' does not exist on type 'unknown'.(2339)

function bar({foo}: unknown) {}
//            ^^^ Property 'foo' does not exist on type 'unknown'.(2339)

try {
} catch ({foo}: unknown) {
  // foo is type any
  // with useUnknownInCatchVariables foo is type unknown
}

🙁 Actual behavior

Destructuring unknown is an error, but destructuring a catch variable, which is of type unknown is not an error.

🙂 Expected behavior

I would expect destructuring of a catch variable of type unknown to produce an error.
