If they can't be viewed as damaged good design (like a bent muffler on a car?), then they should indeed be viewed as reeking of sophisticated design.
You seem to be setting a pretty high threshold with your "reeking of sophisticated design." When we look closely at almost any biological system in an organism we can point out design flaws. Those flaws reek of un-sophisticated design.
What we see is mostly just barely good enough to survive and reproduce design. Evolution has to work with what it has so its design is whatever works is good enough.
Considering that the vast majority of the species that have lived on this planet are extinct, their design clearly does not reek of sophisticated design. Many of those extinct species left descendant species, so their just good enough design was passed on, but in modified form.
not my place to argue why the architect put the sewer so close to the playground.
I don't expect you to understand the mind of your sophisticated designer, I am just pointing out an example of less than sophisticated design, which is what you asked for.

One important characteristic of a theory is that is has survived repeated attempts to falsify it. Contrary to your understanding, all available evidence confirms it. --Subbie
If evolution is shown to be false, it will be at the hands of things that are true, not made up. --percy
