So just to be clear, CLDR *could* support a Europe/Dublin that had an independent metazone with <standard>Irish Standard Time</ standard><daylight>Greenwich Mean Time</daylight>, it's just that synchronizing such a change with the tzdb change is intractable, right?
(that version number field is looking more and more important...)
If we need a single TZ DB zone has changing names time to time, we create what we call "meta zone", and define a set of short/long - standard/daylight /generic name for the meta zone.
That interesting but wasn't really my question. What I was asking, regardless of the semantics of meta vs direct, was whether it would be theoretically workable (in a vacuum presuming everyone can be upgraded to a new tzdb [with winter negative "saving" and summer zero offset standard] concurrently with a version of CLDR data with such a change) for the CLDR to regard a "GMT" with a negative offset as <daylight> and IST as <standard>, even if that would mean it couldn't inherit the translations of "Greenwich Mean Time" from the British zone?
