Make `HierarchyQueryExt` work with `QueryState`
What problem does this solve or what need does it fill?
For exclusive systems, getting multiple queries with query_state is easy and you can pass them world access. However, getting an actual Query, where the HierarchyQueryExt trait is implemented, only works over DeferredWorld, which can easily result in a use of borrowed value here error.
What solution would you like?
Add the possibility to use methods from HierarchyQueryExt with QueryState and &mut World
What alternative(s) have you considered?
#14869
It's not entirely clear to me how this would fix the issue. If HierarchyQueryExt is changed to require &mut World you still won't be able to use it with a DeferredWorld
@SkiFire13 I can use it with DeferredWorld, which is what I do currently. Creating a deferred world, making a query out of query state and using that. Problem here is that DeferredWorld consumes the whole world, which I need for other queries.
This probably plays better hand in hand with #14869 than being an alternative.
