This is just the recovery, completely separate from everything inside the Glass operating system. I've personally used it to install Superuser and Xposed onto my device, but it opens the door to many other opportunities. If Google ever decides to make Glass open-source, then we may see some custom roms, which would be flashed using this recovery.
A publicly available recovery image is the first step toward further customization. If you have no need for it at the moment (you aren't a developer), then I wouldn't recommend flashing it.
