Comment (by goldfire):

 I would say that skolems are a part of the type system. (For example, see
 the "Practical Type Inference" paper, JFP'07.) But the word is utterly
 opaque to users, and I fully support its removal. Or, if it is absolutely
 essential somewhere, the error message should include a link to a page
 explaining what it is.
