I didn't get too many responses to this one, but I had more
or less guessed the outcome. My thanks to the following people
for their input, and those that I haven't recieved yet:

Nickolai Zeldovich
Nikolai P. Iordanov
Daniel Lorenzini

The concensus was that, yes, this is normal. The "tty" user can
be safely removed from the tty group without any ill effects.
