Well, if an extra file contains an information per rule line how to 
interprete SAVE=0 (in case of Ireland: grasping the daylight-entry of 
CLDR which points to the label "Irish Standard Time", default: grasping 
the standard-entry of CLDR) for correct localized labelling then it will 
probably be fine to live without any restrictions so multiply-named 
rules can be avoided.

What about a new file which actually just contains a copy of Eire rules 
with additional META column containing key-value pairs in format 
"season=W" (winter) or "season=S" (summer)? Here stable documented keys 
and values are important, of course. The new file can be safely ignored 
by zic but help other tz-compilers to easily determine localized labels 
of timezones in unchanged CLDR-entries.

I just try to find a compromise with minimalistic impact on all sides.
