Honestly, I don't see any real upside to getting rid of them.

We used to still run some of the _original_ binaries from the old
floppy disk distributions just a few years ago. I honestly hope we
still do. And those old uid system calls would be very much part of
it.

Sadly, I don't know where those old binaries are. Anybody know where
the bash binary from 1991 is? There was a "bash.Z" as part of the 0.01
release.

(Ok, that one is almost certainly broken, but Alan Cox reported
running some really old binaries from the early times long ago before
he turned to even *older* retrocomputing and started concentrating on
the old 8-bit machines ;)
