OOB Security Attributes appear empty

[YvanMartino]

I'm building out a few custom compound Security Attributes, and I'm using some of the below OOB Security Attributes, and I'm finding that they are empty, has anyone else seen this before?
Are we as security_admin users simply not able to see their contents?

Empty OOB Security Attributes

• Impersonating
• InteractiveSession
• LoggedIn

These are known to be empty - the logic is baked into the security attribute engine (java layer) that we can't see as customers

Thanks, I hadn't come across anything that specifically said that.
