I think at first it was just a property that could be set with an
override. Then this was put into a command for convenience
http://lilypond.1069038.n5.nabble.com/grand-predefined-command-thread-td109680.html#a109692
However, the names \arpeggioUp and \arpeggioDown are still free and
would me much more lilypondish.
