The main reason for me was a reluctance to separate version information 
from the data. Separate version files have a bad habit of containing 
wrong values. In contrast, I expect there's less of a problem putting a 
version number into tzdata.zi since that file contains all the tzdb data 
of interest to applications (except for leap seconds, which are to some 
extent versioned separately anyway). It's hard to tell for sure, since 
tzdata.zi is so new.

We could extended the format of zic binary output files to contain a 
version number, and then put the version number there as well. Although 
that might be better for some applications (which ones?), changing 
formats would be more work for all concerned and it's not clear that 
it'd be worth the effort.
