Customizing LO: "finalized" options and the key icon

Hello,

I am currently checking some custom extensions at our site for 
compatibility with LO 4. We are currently using OO.o 3.3 and want to 
migrate. One extension sets several options and locks them down using 
"finalized=true", for example "RemovePersonalInfoOnSaving".

This used to be shown with a key icon and a disabled entry in the 
corresponding options dialog in OO.o. In LO 4 the key icon is not shown 
and the option can be changed, despite it's being reset after the next 
launch.

Am I missing some change here, or has this been dropped from LO?

Thank you,

Andreas
