Or the $newEntityData might be another full entity, for example in its new state.
It doesn't really matter, the algo is always the same: it scans for new keys
in $newEntityData and changed values on existing keys and adds those two things
to the result. 'vp_id' key is ignored by default.
Note: keys may never be "removed" (or marked as removed) in the diff because that
will just not ever happen - the SQL UPDATE command is only capable of sending a change,
clearing a key value at most but never "removing" it entirely.
