I think for 2.4.

Then it sounds like Valentina 1.x also did this semantic mistake.
May be 1.x have correct only RecID...
I hope it is clear that we cannot use ObjectPtr and RecID inside of cursor.
Because if you cast to ObjectPtr then you start to think that you can access
e.g. TargetTable, DeletionControl, but you cannot. You have in cursor not
original field, but its clone
