Is extending SugarACLStrategy working properly in Sugar 11?

:

In the past, I have been able to follow this guide https://enricosimonetti.com/powerful-customisations-with-sugars-acl/. I am trying to make individual rows in a module ReadOnly based upon the values of fields in a Bean. It doesn't appear that the SugarACLReadOnly is working properly in Sugar 11.0.2. Is that correct? Does it not work properly?
