Sure it's comparable. We're not talking about crack teams of dozens of software 
maintainers. We're talking only about a simple script that I wrote in a few 
minutes, a script that can be run automatically. This sort of thing is routine 
in software, and it's not reasonable to dismiss it merely on the grounds that it 
is "packaging/repackaging".

No, as IANA didn't start hosting the data until 2011. Users of these libraries 
evidently didn't have much trouble switching to iana.org, and they won't have 
much trouble switching to joda.org either.

Because we're trying to model Irish time as best we can, and this includes 
modeling Irish Standard Time as standard time.

No, we never had any agreement to freeze the format. The zic input format has 
evolved in the past, and it will undoubtedly continue to evolve in the future.
