That was Stas's original, original proposal way back when. I argued
then for having "default" as a placeholder, and still would today =E2=80=94=
 in
the case where a function with, say, ten optional parameters[0] is
being called and eight of them should be the default, I think it's a
bit rough for somebody inheriting that code to have to count commas.
Having a token increases readability, IMO, and costs us nothing except
a few keystrokes, which isn't going to break the camel's back in a
language that requires "function" each time you declare a function.

will do it, though. :)
