It seems weird to exit() here instead of simply returning a
value...

Why? Within the main() function, "exit(EXIT_SUCCESS)': and
"return EXIT_SUCCESS;" are (almost) exactly equivalent.

Just because it seems odd. It seems cleaner to return
than to exit, but there's no reason for that other than
aesthetics.

<snip>

exit() feels like something that should be
reserved for an error condition.

I wouldn't dream of using it for that purpose. That's what:

return EXIT_FAILURE;

is for. In fact, I can't think of any use whatsoever for exit().

terminating the program somewhere other then main().

As a one -exit-per-funtion person I suspect you wouldn't approve.
