Agreed, the long options *as an alternative* can be descriptive in scripts,
tutorials, howto's etc.
The other reason often mentioned, there being not enough letters in the 
alphabet to cover all possible options, in my opinion advocates bloated 
software (one program can do it all), which goes against the Unix paradigm
of making small programs that do one task exceptionally well and just
chaining these together.
