Now that the old mapping is removed, those 3 will always map to the TZDB data, which has them as valid links in _backwards_ instead of the previous fixed offset zones.

Data conflict with TZDB is not the reason to keep them in `SHORT_IDS`, but they are defined as time zone ids in JDK1.1, as well as others in `SHORT_IDS` is the reason. They are all deprecated, so ideally we remove them altogether, but I expect that would break apps.

That said, it might be useful we log warnings if apps use them, then we may be able to indeed remove them in future releases.
