I don't suppose pipe rusts in your area

Of course it does, but it's less of an issue than galvanized in contact
w/ certain contaminants in gas, hence the historic proscription. I've
heard the flaking and orifice theory before as well, but never found it
codified for that specific reason (that's only saying I'm unaware of
where to find it written, not that it hasn't been).
