The thing I think you are missing is this has nothing to do with
uucp the program. It is just that the default group ownership of
serial ports is 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. (Making a PPP connection
over dialup is a different case.)

In my case, I use serial ports to connect to an old Plam III that I
keep around, a DMM that will send data over a serial link, a data
capture board with a RS-232 interface, a print server with a serial
control port, and HPC over a null modem cable. I sometimes connect
to other things as well. There are a few other things I connect to
from time to time, but this should give you an idea.
