The reason the zones use city names is because city identity is far more stable than national or regional borders. Still, the system can gracefully handle deprecation of a zone name. If Paris is renamed NewNewYork by edict of some new global despot, the IANA will just alias the two names together.

See https://github.com/eggert/tz/blob/main/backward for all the deprecated zones.
