I don't think that is a good idea. We currently put argument default
values in the function signatures in Python syntax, but only because
that also makes sense from a documentation PoV.
We also wouldn't write
 @property
 name(self)
just because that's (one) way for creating properties from Python.

(I am -0 on @positional myself: IMO such a completely different way
of declaring positional-only and keyword-only arguments lacks grace.)
