[tz] zoneinfo vs zoneinfo-leaps

Maybe this is a FAQ but I haven't found the answer.

Having studied up the tzfile(5) format and written some code to produce 
these files, I'm wondering why the files in zoneinfo-leaps include the 
leap records AND adjust the transition times by the appropriate number 
of leap seconds.  This seems redundant to me.  If the file includes the 
leap second records, why not let the consumer adjust the transitions?
