Yes, I was speaking of what you call *suggested* options.  As for now, to
set these options, we should set a default style in compinit or elsewhere.
But since these *suggested* options must be quite uncommon, this is not a
problem. ok.

I must be missing something.  Can't $curcontext be used? 
I am thinking about something like this:

    # 
    _call () {  
      if [[ $curcontext == *:$1: ]]
      then
        $1                   #(A)
      else
        command $1           #(B)
      fi
    }

    _f() {
      _call foo
    } 

    compdef _f foo bar


seems to run either (A) or (B) wheter I complete after foo or bar.
