ContextManager.bind with a dynamic context

[seemk]

I stumbled upon an issue where it would be useful to additionally have a bind method which does not take a context argument, but a function returning a context. It's useful when binding event emitters as some of the emitted events might have different context active based on event types.

What do you think, would there be room for such a method?

Rough sketch (naming, parameter types of the callback uncertain)

public bind<T>(target: T, getContext: () => Context): T

More context here: open-telemetry/opentelemetry-js#2037

Can you provide a motivating example of a usecase which requires such a feature? Not a theoretical explanation but an actual feature you would like to implement.
