I'd argue that currying is actively harmful (I suspect you agree). I've seen functions take one argument in one source file, and the next argument in another source file. In JavaScript no less. Horrendous stuff. One of my most hated anti-features, along with Scala's implicits. These kinds of features are mostly misused rather than used.
