I believe this group should be the authoritative source for such an id. 
What happens when zones split etc? There's presumably a delay between 
the split and an appearance in cldr data.

While we continue to provide only the name as the key to a zone people 
will continue to mistake it for something they can present to users. 
Criticizing such people isn't going to stop it.

Not having a uid in the data means we have no choice but to use that 
'human-readable' key. I'd propose adding a UID to VTIMEZONE - happy to 
write the spec - but at the moment there's no usable value.
