I have never heard of such a thing.

Everything I've seen suggests that the "X" does signify case-sensitivity. It's confusing, if nothing else.

    These file system personalities can be used for erasing and
    partitioning. When specifying a personality as a parameter to a verb,
    case is not considered. Certain common aliases (also case-insensitive)
    are listed below as well.

I meant "trash" in the sense of trying something like "rm Foo" for laughs, thinking that a file "foo" would be safe. (Obviously, on HFS+, you couldn't actually have two files "foo" and "Foo".)
