Why does Redhat's daemon function not have a group setting?

http://unix.stackexchange.com – Background: I'm a Ubuntu/Debian fan and most of my development experience has been on that platform but my current employer uses Redhat. I needed to write a simple init.d script and want the resulting program to run as an unprivileged user. Most resources I found suggest using the daemon function in lieu of start-stop-daemon. Question: Why doesn't the daemon function have an option to set the group like the start-stop-daemon? I'm sure there must be a reason for this, just not sure what that reason is. (HowTos)
