Why should it have to do that? We already have a syntax for
optional parameters, and there is no reason for a reader to
think that a new piece of syntax is simply duplicating existing
functionality.

The fact that a parameter exists in that slot is part of the
API, but the *name* of it is not. This is reflected in the fact
that the comma is outside the brackets and the name is inside.
