That's correct. It's easy, especially in retrospect, to brainstorm every possible feature to make something like this more reliable, but it doesn't take much extra mass, power or development time to end up as a cancelled project. This project very deliberately a different approach under the premise that taking risks, learning, and being cheap enough to try again next time can yield a good result compared to the typical aerospace approach of trying to mitigate and test against every possible risk. It's especially justified in this case because ingenuity probably could not be designed to all the typical requirements and still fly.
