Because, over 15 years, very little of that important old software will be
satisfactory.  Most major OS utilities have a lifespan of ten years or less;
even in that time frame they may undergo several near-rewrites.  All are
eventually rewritten for one reason or another.

Ah, yeah, I have to confess I did that just today.  The nasty old compiler
took my nice mnemonic symbols and remapped them to _B_I_N_A_R_Y _N_U_M_B_E_R_S!  How
uncooperative of it.  Fortunately, my debugger has access to a table giving
my original name and the mapped name.  It is no harder to set up a symbol
table for names that have been remapped to shorter ones.  Have you ever
tried to debug a program that has _t_r_u_n_c_a_t_e_d names?

The prosecution rests...
