Uh... It *has* been, Andr�!! E.g.:

    ...
    White:  G. A. Anderssen
    Black:  J. Dufresne
    Opening:  Evans Gambit
    Location: Berlin, 1854
	White       Black
       -------     -------
     1. P-K4        P-K4
     2. Kt-KB3      Kt-QB3
     3. B-B4        B-B4
     4. P-QKt4      BxKtP
     5. P-B3        B-R4
     6. P-Q4        PxP
     7. O-O         P-Q6
     8. Q-Kt3       Q-B3
     9. P-K5        Q-Kt3
     ...

Although I will admit that this notation (which I learned as a child)
has been superceded lately amongst professionals by what is called
"algebraic chess notation", e.g.:

    ...
    This is Kasparov versus The World, a game played by Garry
    Kasparov over the internet against the rest of the world
