Understood. So is the description of 'sync-cycle' and its values above okay?

Agree, but it's not technically feasible.

That doesn't help. When I do a PullAll(), even if it is in the same PBAP
session, I get no information about which vcard refers to which contact. I
still need the text properties in the vcard to find that match a second time.

There are two different feature request here:
1. make incremental syncing more flexible such that any property can
   be turned off during a sync without removing it locally; PHOTO
   is currently the only property where that is possible.
2. configure the set of properties that the local side is interested

This sounds similar, but the implementation is different. The first one
involves sync logic, the second only one the set of data retrieved from the

The first one is harder. Right now, specific code has to be written for each
property which shall get that special treatmet. Adding more of them would get
ugly pretty soon.

Can you name a specific use case where you expect this to be beneficial?

The second one is already possible internally, there just isn't an API for it.
This would go into CreatePeer().

Either way, for the sake of avoiding feature creep, let's not mingle that into
this issue here. If you want this features, discuss their importance with your
colleagues and file new feature requests.
