FWIW, I always thought of it as being for portability of humans, and was very grateful for it on Windows. A large chunk of my time is spent on *NIX systems, so my fingers automatically type "ls" and "rm" instead of "dir" and "del". The fact that Powershell worked, rather than throwing a "eh, what?" error made my time on Windows suprisingly more pleasant.
