I totally get your point and it's valid. But I think this ship has sailed a long time ago.
With modern languages having adhoc polymorphism, inheritance and different kinds of dispatch as well as extension methods etc., without an IDE you are already lost anyways.
E.g. in rust you won't know where a trait is implemented and how it will behave, in kotlin you won't know if a method exists on the object or comes from somewhere else etc.
The trend is going to more supportive but also more complex languages and tooling is naturally adapting to that.
