I think many people confuse "ship it" culture with just doing crap work. I've seen too many ship it projects die because the biggest feedback from the customers was "This thing doesn't actually seem to work" or "This is useless". Ship it can apply to hard problems as much as easy ones, it's more about not doing extra work before you know what your customers want. But if you MVP it to the point where it barely works and has no real functionality then customers will often view it as trivial and useless and you'll likely confuse missing product market fit with under delivering.
