I think this is a good example of the analogy falling apart. A feature that is 99% done may actually be fine. Or it may not be much better than 0% or 50% - that sort of depends on the business side and how incremental a given feature can be and still provide value.
Still, I think in general it's a good idea to be a little more on the "finishing mindset" of things than the "if it builds, it ships" side of things.
