I think checking that a value comes from a particular enum *is* a degree of
hand-holding.  For libraries or frameworks whose users aren't expected to
know them exhaustively, making reasonable checks of parameters can
substantially reduce the number of ways it can be used incorrectly.  Outside
performance critical code, this is a win.
