If I understand you correctly, you're not concerned about tzselect 
(which is text-only). Instead, you're concerned about a graphical user 
interface that shows a map of cities without showing timezone regions, 
or perhaps shows timezone regions that don't match the actual (but 
undocumented) tzdb regions well.

I would say that such UIs have always been problematic, as inaccurate or 
missing region boundaries can make such maps difficult to use. Although 
this has long been true (as witness the South Pole example), I don't see 
why it means we should drop coordinates from zone1970.tab (coordinates 
that tzselect uses and which graphical UIs can also use); all it means 
is that those maps and/or UIs could use improvements.
