I kept the tuple as the accepted option, but I am personally open to

My "vote" is for NoIndex. I suggested that new object and name, after
all :-).
But I find empty tuple perfectly fine, and would have no objection if
that is chosen.
I'd go for something that would have a wider use.
Consider, for example, the use-case of a function that has an optional
parameter and you want a way to know whether an argument has been
provided but None is a valid value that could be passed in.
Having a singleton such as Missing would be helpful there.
An index/subscript that has no positional component is just a special
case of that.
