Plan B for ListPathObserver?

[fabiosimeoni]

I've searched long and hard, but couldn't find much information about why ListPathObserver got to be deprecated (besides that it's has been removed from observe-js), or indeed what's the recommended alternative.

I guess the use cases for it remain as valid as they seemed to be. For example, computed sublists based on values (deeply) inside their members.

Do you see that as a bad practice? Outside the scope of the package? Or is it covered otherwise?

cheers
