Is there an easy way to wrap a

MutableStateFlow

so that I can do something with new values before they are sent downstream? E.g.

fun <Value: Any> persistedFlow(key: String, serializer: KSerializer<Value>): MutableStateFlow<Value?> =
	save(MutableStateFlow(value = load(key, serializer)), key, serializer)

How would I implement

save

? According to the docs:

The
MutableStateFlow
interface is not stable for inheritance in 3rd party libraries (…)

Well, if you need stable api in your library you cannot implement MutableStateFlow
