Maybe we can add some way to record general preferences, or maybe just asking people to define a wrapper function to put the disambiguation in one place is fine.

I’m not sure what you mean. How does changing the declaration site solve the disambiguation problem at the call site? (And how do you think Swift extensions differ from C# extensions?)
