Question (People API) : any way to query the otherContacts list by time updated?

[AndroidDeveloperLB]

Or maybe it's already sorted as such?
I want to cache the results and later if there is none on the query, ignore them all.
Or to update what's cached when possible.
This is why I also need some ID for each, but no idea where can I get it.

I'm talking about the API of OtherContacts.list() , which matches to this, and returns me a list of Person (relevant link here)

Seems the list is sorted from oldest to newest, and that using the sync-token we can get what has changed.

But, the sync-token doesn't say which were removed. Only a list of contacts is returned (modified/new).

Can you please offer to sort in the opposite direction (from new to old) ? This can help in case we've cached the results, and need only the newest ones (and don't have a valid sync-token).

In addition, for sync-token, please offer a way to detect which were removed, because this seems missing and can only be found if I query the entire list again.
