I'll limit this package-private method to only `NumberFormat`, since the other eligible XXFormat classes, `DateFormat` and `ListFormat` both utilize a style enum and thus such a method is not needed for them, as we can just iterate through the style enum values.

Since `NumberFormats` style enum only applies to compactNumberInstances, it can't be used in a similar fashion.
