I’d argue that people who are not familiar with “iff” are usually unfamiliar with its full version “if and only if” as well and, unaware of the need for such distinction, tend to treat regular “if” as bidirectional. These two mistakes will cancel each other out and they won’t miss said something key.
Agreed. I think this basically makes concerns about “iff” being mistaken for “if” irrelevant and trying to make a better shorthand for “if and only if” is a distraction with insufficient impact for most anyone to trouble themselves with.
