You're absolutely right! I built this mainly to see if it could be done. I noticed uvicorn's main function uses an if-statement like you described, and I wondered what it would look like as a decorator.
My next goal is to see if I can make the resolution "static", i.e. Once all the functions are loaded, avoid the dictionary lookup at runtime, and just assign the appropriate function version as the bare module attribute.
It's fun to do things like this in python, simply because you can. But it's also important to point out that there's a lot of things you _shouldn't_ (this may be one of them!). I'm glad to see this sparked some discussion!
