This is very true, there are numerous 'design flaws' that are well known in humans* and other animals, that occurred via the process of evolution. Realistic hypothetical alien lifeforms should not be optimal in all facets.
* for example, breathing via an orifice used to ingest food and water is clearly unwise engineering, as evidenced by the number of people who choke to death from various food and drink based misadventure.
