When was theTime Zone Name (TznGeoRefTe) for America/Aruba obsoleted?
Sorry, I don't know what a TznGeoRefTe is; that notion is not part of tzdata. I expect the notion comes from some downstream use of tzdata, and perhaps you could ask whoever is in charge of that downstream version what happened to Aruba in their downstream copy. In tzdata America/Aruba is still there, and is an alias for America/Curacao. This alias was created in tzdata release 2013e dated 2013-09-19 23:50:04 -0700. Formerly America/Aruba was a separate zone, but its data were unreliable and out of scope for tzdata so it was turned into a link. Notification for the change is in the NEWS file distributed as part of tzdata.
Are all countries identified in IANA with a Time Zone Name (TznGeoRefTe)?
No, not every country with a two-letter country code has a time zone identifier. For example, Bouvet Island (country code BV) has no time zone identifier, as it's uninhabited. Although we formerly tried to give every country an identifier, counterexamples like Bouvet and political disputes about what constitutes a "country" have put something of a damper on that idea, and the topic is controversial.
