Unique IDs that are not really unique are the beginning of all evil, and there is a special place in hell for those that "recycle" GUIDs instead of generating new ones. Having ambiguous names can likewise lead to disaster, as seen here, even if this incident had only mild consequences. (Having worked on place name ambiguity academically, I met people who flew to the wrong country due to city name ambiguity and more.) At least artificial technical names/labels should be globally unambiguous.
