This seems unduly pessimistic to me.  If zic writes an additional file
into the target directory, that would probably automatically get included
by most packagers --- it'd look no different from a new zone file.  And
I doubt many packagers are left who haven't set things up to just
automatically include new zone files.  As an ex-packager (not of tzdb
though) I can tell you there are lots of better things to spend time on
than micro-managing your upstream's file manifest.  Especially for an
upstream such as tzdb, where changes in the file list are everyday
occurrences.
