Yes, that's right.  If Chile intends to stay on DST permanently, the 
usual practice is for the tz database to model that as the new standard 
time, effective when the rules change.

Yes, we can do that as more information comes in.  Presumably this won't 
affect UTC offset, it's only an issue of the English-language alphabetic 
abbreviation and the tm_isdst flag.
