When a task is updated, the position of the tasks of the whole project/bucket are updated. This leads to column "updated" of model Task to be updated quite often. However, that column is used for the ETag field of CALDAV.
Thus, changing a task marks all the other tasks as updated, which prevents clients from synchronizing their edited tasks.
