Please, do not remove it.
For most of users, this option is not useful.

However, developers need to be able to set the value (usually at a low value like 2 or 3) when the
undo/redo has an issue (usually related to object deletion), even in release mode.
Sometimes a crash can happen when objects in undo/redo list are deleted, if there is a bug in these
functions.
