This is no longer an issue due to a change in the galvanizing process which happened several decades ago. None the less, it would be wise to check with the governing authority for your jurisdiction. Until about 30 years ago, copper was unapproved for natural gas piping in my jurisdiction. It is now approved.
You maybe right that it is an old tale at this point nevertheless many jurisdictions do not allow galvanized pipe
