FB9126221 (NSFileProviderReplicatedExtension enumerators limit its use cases as replacement for "real" VFSs)

As a already wrote: I e.g. use this function in a loop. Memory is not released.
I found this example, which looks promising: https://github.com/peterthomashorn/macosfileproviderexample/tree/main
Still, having an example how to use the new NSFileProviderReplicatedExtension would really be helpful.
As long as Apple does not provide an official sample code, @Laszlo, @sssddgg could you maybe post your code here as a starting point for other developers? Thanks a lot!
Apparently the legacy KEXT is still loading!? Please see related question. - https://developer.apple.com/forums/thread/667692
Please see also related question: Memory buffers deprecated? - https://developer.apple.com/forums/thread/665754#665754021
It refers to the same project.
