Admittedly this seems unlikely, but on the other hand I find it reasonably plausible that Karl and I are the last two people in the world using uucp. > Now, if you need to use the serial port for > anythings as a user, be it dialing into some site with a modem, or > talking to another system, router, pint server, etc over a serial > port, you need access to the serial port.

I used to use my serial port to connect to a geiger counter. I must try to find out where that has gone ... I must say, I always hated serial ports, with endless nonsense about the speed, and whether they were using 7- or 8-bits. SLIP was a nightmare, even worse than WiFi. Although I am in general against progress, this is one exception.
