Now i see your point.
I have implemented the same patch using only KConfigGroup but because of the "scheduleConfigSync" there is a case where the sync cannot keep up with the change of the activities - leading to a weird behavior (the changes are not yet made volatile).
That could be solved by calling "configSync" explicitly but that could affect the performace? (no idea).

To sum up: i think it is faster and less error-prone to store in memory and sync whenever sync is scheduled to, than to read/write whenever an activity is changed.
