Why are QueryCache Interfaces not exported?

[maertu]

I would like to use those interfaces in my application for processing QueryCacheNotifyEvent. Unfortunately they not seem to be exported. Is there a reason for this?
If someone cares why I would want that: What I am doing is subscribing to the queryCache and if a change is made I update some canvas elements manually. For this I want to do a proper processing of the QueryCacheNotifyEvent. Having access to that interface would make things easier.

query/packages/query-core/src/queryCache.ts

Lines 22 to 70 in 3c9df20

	interface NotifyEventQueryAdded {
	type: 'added'
	query: Query<any, any, any, any>
	}
	interface NotifyEventQueryRemoved {
	type: 'removed'
	query: Query<any, any, any, any>
	}
	interface NotifyEventQueryUpdated {
	type: 'updated'
	query: Query<any, any, any, any>
	action: Action<any, any>
	}
	interface NotifyEventQueryObserverAdded {
	type: 'observerAdded'
	query: Query<any, any, any, any>
	observer: QueryObserver<any, any, any, any, any>
	}
	interface NotifyEventQueryObserverRemoved {
	type: 'observerRemoved'
	query: Query<any, any, any, any>
	observer: QueryObserver<any, any, any, any, any>
	}
	interface NotifyEventQueryObserverResultsUpdated {
	type: 'observerResultsUpdated'
	query: Query<any, any, any, any>
	}
	interface NotifyEventQueryObserverOptionsUpdated {
	type: 'observerOptionsUpdated'
	query: Query<any, any, any, any>
	observer: QueryObserver<any, any, any, any, any>
	}
	type QueryCacheNotifyEvent =
	| NotifyEventQueryAdded
	| NotifyEventQueryRemoved
	| NotifyEventQueryUpdated
	| NotifyEventQueryObserverAdded
	| NotifyEventQueryObserverRemoved
	| NotifyEventQueryObserverResultsUpdated
	| NotifyEventQueryObserverOptionsUpdated
	type QueryCacheListener = (event: QueryCacheNotifyEvent) => void

Little side question, if maybe someone is able to answer. Is there a built-in way to read the previous value before this event changed the cache? I looked into cacheEvent.query.state.data cacheEvent.action.data and queryClient.getQueryData(["xy"]) but they all hold the new value.
