captureStoreUpdates — return the full path to the property that changed

[astoilkov]

Describe The Problem To Be Solved

I'm migrating from on-change to using captureStoreUpdates().

When using captureStoreUpdates(), setting a new value mutable.settings.model = model will produce the path: ["settings"]. However, if I replace the entire settings object this will trigger more updates than just updating the settings.model property.

Suggest A Solution

I propose for an option or change in behavior where setting mutable.settings.model produces path: ["settings", "model"].

captureStoreUpdates is returning the path to the object, not property, by design. It allows to simplify the implementation a lot—there is no easy way of checking which property was changed without cloning each object and diffing it.
It's not properly communicated in the readme, which need to be corrected.
I'm also not against adding another helper for diffing the objects that would wrap captureStoreUpdates. But captureStoreUpdates should remain as is, because getting the changed object is often what you need.

I would choose the simpler implementation as well.

It would be great then to have another helper as well. However, if this isn't something you are interested in at the moment you can close this issue.

Thanks for the detailed explanation!
