The issue isn't "how many people will actually care", it's "why write yourself into a bizarre corner in the first place"? Because some part of the audience does care, and even for the part who care less, you've created an issue that can cause a problem, and we can see it has caused problems. It's not a disaster, it's just basically silly/incompetent.
That comicbooks ignore this sort of thing is a part of why supers comics have basically become a hobby for 35-54-year-old men, rather than a big cultural thing that a huge proportion of kids regularly read.
