I am writing some extension functions to work with

Flow

and platform-specific API's, e.g. the web broadcastchannel API. However I choose to pass

CoroutineScope

when needed, but this leads to code like this:

states.broadcast(channel.deserialize(scope), scope)

Is it a code smell to have these kind of scopes everywhere? Or is it not a problem. My intuition says that it is not a problem, because this way I can easily control the scopes and no magic happens. So I can keep the structured concurrency.
