I have already pointed out that it is wrong to link Europe/Vaduz with 
Europe/Zurich

Vaduz (Liechtenstein) is a different country, with a different timezone 
history: no DST in 1941 and 1942. It should not be linked with Zurich, 
Switzerland.

I do not understand why the current zone for Vaduz, which is correct, 
should be thrown away and be replaced with a link to an incorrect zone.

This is against the Theory rules, as pre-1970 differences are supposed 
to be only ignored for areas belonging to the same country.
