No worries, just want to try and be clear on these things.. Too easy to
mistakenly think that doing this very-similar-thing will be as secure as
doing the recommended-thing (particularly when the recommended-thing is
a lot harder...), and we don't want to end up doing that and then
discovering it isn't actually secure..
Thanks!
