It is nice for maintaining scripts though. While short names and options are typing-savers interactively (though sometimes problematical when a single character typo can radically change the meaning of a command in a way that means it is still a valid command so will be executed) in scripts I want long names so people after me (including future me) can understand without reference to man pages or similar. OK, the same could be achieved with copious comments, but then you have lots of pairs of bits of text to keep in sync.
