People keep removing UNIX code

But let's face it, the code was never removed. The authors of the documents don't know which direction time flows in. Here's a clue to the first one about v6. If you look in v7 you see:
sysent.c:       0, 0, nullsys,                  /* 39 = setpgrp (not in yet) */
Oops, it wasn't removed--it had not been added yet. Similarly nobody removed termcap from SysV games, it hadn't been added yet either.
