To the original post... I would say, no, people don't really care.
I mean, I'm sure there are some people that may actively look for these things for whatever reason, but most people are more worried about their own imperfections, like their own heights, builds, and things. And even those that aren't preoccupied with their own difficulties probably won't look twice at others' imperfections... After all, everyone has them.
I'm not sure if there's any benefit to worrying about what we see as faults. If they are things that can be changed, then the worry is there to remind us to fix the fault... but worrying about the things that cannot be changed is just something to work around, so that the concern can be refocused on more important things, like working on being better as a person, and developing traits such as patience, adaptability, compassion, and others.
I would be paraphrasing, but a wise man once said, "What has worry ever profitted a man?" It's a simple question, but when we look at how the worry is benefitting us, we can realize that worry is a silly thing.
... I try to apply that to my own journey. I do worry about it, and I'm a little afraid of what may happen at times, but I realize the value of being able to move ahead without fear, and accept whatever may come my way -things will probably happen, and they might be unpleasant, but I will just have to deal with it, and do so with as much grace and tact as I can find inside.
(Of course, there's a difference between worry and contingency-planning. Definitely don't rush ahead without a plan for the not-so-good-case scenarios.)
... Just my thoughts. You know, sometimes I feel like these replies get rambly and nonsensical... I just hope I contributed.
