Is there a more idiomatic way to have a wrapper around an HttpClient that sets up some default features, but also allows some use-site customization? More in a thread, but basically I want to be able to create an XClient which might be backed by a CIOEngine...but also be able to use the same class but with a MockEngine, which requires being able to add handlers

I've got an abstract class like this

Then impl classes look like this (adding additional features)

Which then allows customization at the use site like this:

But the stuff at the abstract class feels very weird and unergonomic

Guess I answered my own question, making the second parameter on the abstract class

engineCustomization: EngineType.() -> Unit = {},

which then makes the client initialization

protected val client: HttpClient by lazy {    HttpClient(clientSupplier.create(engineCustomization), clientConfiguration)
}

makes things a lot nicer to look at

Just kidding, that can even be reduced further, because HttpClientEngineFactory has a create extension function, so you don't need to provide a configuration lambda at all
