If you're open for alternatives, framing it in in a way like "I know you're trying to accomplish X, but due to Y, I think the outcome is more along Z". So something like "I know you're going for a soft launch, but without providing a more concrete and demonstrative user experience, the current status of the project is more of a tech demo".

This approach acknowledges what the person is trying to accomplish, and lays out the obstacles before arriving at the conclusion, which then feels more natural. The recipient is able to follow your thinking and hopefully "arrive" at the conclusion along with you. When you start with the conclusion, you risk having a jarring moment where you start with something unexpected, and that can generate friction.
