BehaviorVersion's interface is not as future-proof as the doc says

Describe the bug

It is possible to construct a BehaviorVersion:

Using the following syntax:

let behavior: BehaviorVersion = BehaviorVersion {};

While the documentation says that latest may change behavior but v2023_11_09 would keep its behavior, that is impossible because one cannot add new fields to BehaviorVersion without that being a breaking change due to the currently allowed explicit construction.

Expected Behavior

let behavior: BehaviorVersion = BehaviorVersion {};

should not compile, one should be forced to use either latest or v2023_11_09 to instantiate a BehaviorVersion.

Current Behavior

compiles

Possible Solution

That should be achieved by defining the struct as so:

pub struct BehaviorVersion {
    _private: (),
}

Additional Information/Context

This is technically a breaking change but since this was released recently and it's documented that this API shouldn't be used, better now than later.
