Introducing new overloads with @SinceKotlin(1.4) annotation and marking the old ones @LowPriorityInOverloadResolution breaks all code that uses the format(locale, args) overload with -api-version 1.3. Because the low priority of the non-1.4 version makes format(args) preferable in all cases. For example, "%02X".format(Locale.ROOT, 1) throws IllegalFormatConversionException: x != java.util.Locale.
