Isn't it too much? The PEP clearly indicates '=<optional>' is just
a notation for an optional parameter.
If it's that much of an issue - We can use '=_void' instead, as it is 
in the implementation, and describe how it works. But that's just noise,
that will distract the reader from the PEP.

That may confuse someone, as ... - Ellipsis is a legitimate object
to be used as a default value or annotation:
 def foo(bar:...=...)->...:
 pass
I'd keep it simple ;)
