It was for a while the editor of last resort, which you could use to rescue a system in a parlous state when only the root partition was available, but not /usr. That's gone out of the window nowadays where /usr is rarely a separate partition and we have more modern filesystems like ZFS which have the useful property of never being rendered unmountable by a sudden system crash. (You don't get off Scott-free though. Instead, you can loose the last few updates to the filesystem in those circumstances.) Even for scripting purposes, sed(1) rules the roost. I don't think I've seen a script using ed(1), well ... pretty much ever.
