It is too early to propose this as a new zone for tzdata.

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.

For Busingen, only the exception in 1980 is confirmed by research.

It is not yet known what this exclave did in 1941 - 1949 and in 1916 - 
1918 when Germany had DST / war time  but Switzerland did not or did 

I have written a few days ago to Busingen authorities in the hope to get 
information about its timezone history.
