Definitely not true, it works here without being root, but:
$ eject
eject: unable to find or open device for: `cdrom'

$ eject /dev/sr0
works

$ eject -T /dev/sr0 (while tray is ejected)
eject: CD-ROM tray close command failed: Input/output error

$ sudo eject -T /dev/sr0
Password: 
eject: CD-ROM tray close command failed: Input/output error

or anything else that should pull the tray back in doesn't work on my
machine, according to 'man eject' this may simply be a hardware
limitation.

Nothing was mounted in my test case, there's no CD inserted. I do
somewhat understand the behavior of my machine but not the behavior on
the original posters machine. In any case, root/sudo is not required.
