I don't understand :/

I don't think it's easier, cause this is multi-account. so you still
have to parse answer from several accounts.

There can't be out-of-sync lists: on each server you store data only for
contacts in this server. This way data are not duplicated, and you don't
put a part of your contact list on another server (privacy issue).
