It is too early to propose this as a new zone for tzdata. Too early to be included is one thing, but  too early to be proposed, is another thing.

I think people are free to submit  proposals at any time.

The practice for each zone in tzdata is that also the complete history  from the beginning of standard time must be included in the zone file.

1) Alois Treindl 2011-08-30 14:40:48 GMT: "I have compiled a complete  timezone history of Germany." http://article.gmane.org/gmane.comp.time.tz/3951 Buesingen is part of Germany says  http://www.buesingen.de/ "Büsingen am Hochrhein ist, wenn auch ringsum von  Schweizer Hoheitsgebiet umgeben, deutsches Hoheitsgebiet" 2) I see no proof that it is practice "that complete history from the beginning of standard time must be included in the zone file." 3) I see no statement in the Theory file nor  in README that would require such a practice. To the contrary, Theory file says: "As noted in the README file, the tz database is not authoritative  (particularly not for pre-1970 time stamps), and it surely has errors. Corrections are welcome and encouraged." README says: "The information in the time zone data files is by no means authoritative; the files currently do not even attempt to cover all time stamps before 1970, and there are undoubtedly errors even for time stamps since 1970. If you know that the rules are different from those in a file, by all means feel free to change file (and please send the changed version to tz@elsie.nci.nih.gov for use in the future)." 4) I did not edit the file(s) in question since I don't know how to structure it. I hope someone with more knowledge can help to  fix the current error for 1980. Additional pre-1970 imprecisions  remain open to be fixed, the fix I propose does not hinder future progress. Little geography fix for my other email:
