This is the kind of argument that keeps on coming up. Everyone has a "What if" scenario about function annotations... and almost nobody actually has a codebase that uses them. It's equivalent to asking: "What if I already used docstrings to control URL routing, and now I want to use them for function documentation?". Well, simple. You move your other-use-of-annotations out to something else (probably a decorator) before you add type hints. Until that time, you're welcome to continue using annotations for something other than type hinting; you just can't do both at once on the same function.
