There's a long hallway between the spawn room and the rest of the maze. So if you are almost dead and got someone chasing you, I doubt you will make it back to the spawn room. But sure, that should be the place where it's safe. Like when you need a 2 minute break to go get a beer, you can go into the spawn room and don't have to worry about dying. I see nothing wrong with this.

Here's an idea.... If you got the flag you can't go into the spawn room. Otherwise you are free to go there whenever you want.
