I would be fine with that result. My objection is when people say "I'm just not good at X," when what they really mean is "I'm not as good at X as I think I should be, that frustrates me, and I lack the motivation to continue trying." If we can demonstrate that with enough practice, anyone can get good at anything (with a large delta of good), then I think that's meaningful.
If that statement is self-evident to you, I've talked to people who don't consider it so. For example, I've talked to other CS majors who think that most people just don't have the right "mind" for programming, and I've taught programming to people who said similar things.
