I meant the extra code for writing a special class to handle scalars, if I decide that the "x[()]" syntax is too ugly or too hard to type, so I write a special class which will allow the syntax "x.value". The extra parentheses might not seem to matter for code using that library, but I intend for people to use it directly, in an interactive way, just like you type an expression in a spreadsheet. I expect that for such a usage, the extra parentheses will be slightly unfun. I know that it's not such a big difference, but I'm not talking about a big change to the language either - it affects less than 20 lines of code (probably could be done with even less), and doesn't cause any problems with anything. I can imagine Guido designing the grammar, thinking, "Should I allow an empty subscript list? No, why should anyone want such a thing? Besides, if someone wants them, we can always add them later." - at least, it may be how I would think if I designed a language. So now, a use was found. Indeed, it is farely rare. But why not to allow it now?
