A Typechecking consumer and a PyPy compiler consumer might work on the same annotations because they are both interested in TYPES (but doing different things with them). These type consumers might also choose to implement more than one type checking syntax, if there were a good reason that more than one arose (perhaps Unix types versus .NET types).

A docstring consumer and a typechecking consumer would by definition use different syntaxes/frameworks/wrappers because the information that they are looking for is different! But there could be hundreds of docstring consumers (as there are today!). Docstrings are a special case because the syntax for them is fairly obvious (an unadorned string).

So basically what you're saying is that there would be a more-or-less standard wrapper for each application of function annotations. How is this significantly better than my dict-based approach, which uses standardised dict keys to indicate the kind of metadata?
