Do you use auto-update for MATLAB Objects?

The MATLAB object system has a feature called auto-update. If you create objects of class A, then update the definition of class A, all existing objects of class A automatically get the new definition. A few questions for the community.

• Were you aware of this feature?
• Do you use the auto-update feature of MATLAB objects?
• How do you use this feature?

I was aware because I've noticed its effects, and I use it with an air of trepidation.

If adding a property or a simple method, I might continue working with the current object as I develop the class, but I don't do anything creative with auto-update. I've not thought before tonight about how it would work with, for instance, a modified constructor. In uncertain situations it's not usually much of a hassle to simply regenerate the object.
