It is verbose so you can find new commands on your own, and so you know the general function of something by its name. If someone learns the help system (get-help) and command discovery (get-command), it is usually easy to find a command. All information retrieval commands start with Get. All commands that change settings start with Set.
Please tell me, because I have a lot to learn in *nix, how would I figure out to use chmod to change permissions if I was previously unaware of the command name? How do I discover the correct commands without asking someone online or offline? By the way, the command to change file permissions (or other system object permissions) in PS, set-acl, is really unwieldy. If I were having to use it a lot on the fly in the command line, I would probably end up writing a helper function to make it simpler to supply the user and permissions level.
