The thing is there is never "no intention" - there's only "no intention at the moment". We don't have a crystal ball to know how things will go in the future (user interest, finding good developers who want to do this as a project). So we can't say "never an intention". If we say "no intention at the moment" then that would mean it would be at least 2 or 3 months before work could start (assuming the perfect situation of a developer contacts us, wants to join, passes the interview, wants to work on this as a project, joins the company, gets up to speed), and then another 2 or 3 months before something was usable even in early form.
So if a third party developer wants to create an exporter, they know they have quite a large window in which to work if we've said "no intention at the moment". However we just can't say "never" because then if things change and we do decide to work on it, people would complain - and since we really don't mean "never" but just "not at the moment for sure" then we have to be honest and say that :)
