I greatly dislike case-insensitivity. It's a source of many problems for users and implementors.

For implementors case-insensitivity means the need for full Unicode support is urgent, while Unicode canonical equivalence does not often make the need for full Unicode support urgent. In practice one often sees case-insensitivity for ASCII, and later when full Unicode support is added you either have to have a backwards compatibility break or new functions/operators/whatever to support Unicode case insensitivity.

For users case-insensitivity can be surprising.

For code reviewers having to constantly be on the lookup for accidental symbol aliasing via case insensitivity is a real pain.

Just say no to case insensitivity.
