No, it is customary that C-u changes the behavior as a function.
Admittedly Org does this more extensively than other programs.

Yes, for your command name listing this is a problem.

Two cases

1. Using prefix arguments actually internally calls a different command.
    Then one can try to find this command, and if it can be called in a
    stand-alone way, it would actually be useful to give this indirect  
command
    in the list

2. The prefix argument just modified the command a bit - here I think
    we have no choice but to repeat the command name as it was given  
for the
    un-prefixed call.  Normally one would in fact describe the effect  
of the
    prefix arg in the description of the un-prefixed command.  But  
sometimes
    I have found it useful to list the prefixed call explicitly.
