Thank you for the information. But i think there is a flaw.

There are IMHO two cases. the user deletes the share, and the user is deleted:
I will begin with the second

2. If the user is deleted the user is unable to authenticate/synchronize
    and any other user that might have had access to the share will have
    lost it, as the  entriy in *_sharesng and *_shares_users are deleted
    with the share

1. If the share is deleted by the user the synchronizing would/should
    fail as the ownership/permissions for the share cannot be resolved.

So your argument that "any synchronized clients would never have the  
data removed"
is true with and without the data in horde_histories.
