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

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

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.

If it is really true that from now on, you want to ingnore differences 
between countries, if they apply only to pre-1970, when since 1970 the 
two countries agree, you would also have to remove Europe/Paris and link 
it with Europe/Berlin, because since 1970 these two zones have not differed.

The same appleies to MANY central European zones, which all agree since 

It would be a horrible loss of correct history information in TZ.
