There was no reason for this in the first place in my opinion. The ONLY positive use I can see would be managing the whole arr stack from one place, but I imagine you would still need to manage individual shows\movies\whathaveyou if it wasn't found in the first place.

I have my stacks set up to auto upgrade and find missing stuff already. It's literally built into their programming. I manage them individually and anything that isn't found on my indexers I typically go out and find manually as needed (old or very obscure media).

Not really sure what this bought anyone at all other than an extra layer of convenience?
