"Point person?"

This from the New York Times: "Mr. Wisner, who consulted closely with the White House, is expected to be the point person dealing with Mr. Mubarak as the situation evolves, and perhaps as the administration’s message hardens."

When did "pointMAN" fall out of style?  Does the inclusion of "man" so offend as to dictate a change in over a hundred years of usage?  Is  "Fore-person" or perhaps "right hand person" next?  Good gosh.
