Case-insensitivity is annoying to me, and much more difficult to implement than case-sensitivity. Yes, yes, one should always implement Unicode normalization or at least form-insensitive comparisons, but that's a subtly different. Even if you implement normalization / form-insensitivity, case-insensitivity still requires significantly more constant data tables. And you really have to have normalization support if you're going to do case-insensitivity.
