Noticed that converting between certain calendars is not supported. Was that choice intentional?

    const today = Temporal.PlainDate.from("2569-03-11[u-ca=buddhist]"); 
    today.toLocaleString("en", { calendar: "hebrew" });
    > Uncaught RangeError: calendars "buddhist" and "hebrew" aren't compatible
