Thank you very much for your answer. I understand the concern to
minimize the count of identifiers where possible. However, now the
question arises if the rules of outdated Asia/Hanoi will be updated,
too, if for example the rules of Asia/Ho_Chi_Minh might change in the
future. Will the rules of backzone-identifiers be adjusted to future
changes or not?
I would take an answer to this question into consideration to decide if
I include the backzone-file into my future tz-distributions or not.
