You will no longer be able to combine style: "percent" with unitWidth:

new Intl.NumberFormat(undefined, {
  style: "percent",
  unitDisplay: "long"  // Read, but ignored.
});

new Intl.NumberFormat(undefined, {
  style: "unit",
  unit: "percent",
  unitDisplay: "long"  // This is OK
});

There should be no unit or unitDisplay field in resolvedOptions:

new Intl.NumberFormat(undefined, {
  style: "percent"
}).resolvedOptions();
// should NOT contain a unit or unitDisplay field

percentSign is no longer allowed in formatToParts in style: "unit", but it is still OK in style: "percent":

new Intl.NumberFormat(undefined, {
  style: "unit",
  unit: "percent"
}).formatToParts(100);

// Expected: [
//   { type: "integer", value: "100" },
//   { type: "unit", value: "%" }
// ]

What is "unitWidth"? Do you mean "unitDisplay"?

new Intl.NumberFormat(undefined, {
style: "unit",
unit: "percent",
unitWidth: "long" // This is OK
});

There should be no unit or unitWidth field in resolvedOptions:

new Intl.NumberFormat(undefined, {
  style: "percent"
}).resolvedOptions();
// should NOT contain a unit or unitWidth field

Yes, sorry, my bad. Getting the ICU name mixed up with the 402 name. I'll edit my post
