Ultimately, official and/or public usage will determine the names that 
are actually used -- and presumably the tz database will track that 
actual usage.

IMO, if the EU decides to mandate that its member states must cease to 
observe summer time, and the EU or the member states further decide (as 
would seem quite likely) to keep using WET/CET/EET as time zone 
abbreviations then, given the importance of the EU within the wider 
European region, any non-EU countries using one of the current 
WET/CET/EET will have little choice but to align with the changes or 
find a new name for their time zone.
