The alternative for useQuereies keepPreviousData in v5

[RichardPanP]

Hi, I'm upgrading @tanstack/react-query to v5 and noticed that keepPreviousData has been deprecated. And there's a note that useQueries would not receive previousData in the placeholderData. Is there any way if I still hope to keep the previous data in useQueries?

keepPreviousData on useQueries wasn't really working in v4 with dynamic length arrays. It's too difficult to find out which observer was the "previous one" when lengths change. we removed it for that reason.

Are there any patterns or code examples you can recommend to replace this behaviour for those of us performing the migration to v5 who relied on keepPreviousData inside useQueries? For instance this blog was quite useful to migrating away from the callbacks which were removed from useQuery; is there any equivalent write up for this topic?

if the queries are known - use multiple useQuery calls. If they are truly dynamic, try to split them up into separate components.
