Hi,
the first usage of limited doPrivileged appears to have a small startup penalty
(loads 8 permission-related classes and does some reflection), and is arguably
excessive for this particular instance. Unrestricted doPrivileged allows for a
small reduction of lambda init cost.

I agree that getting system properties isn’t a good usage example of limited
doPrivileged since the permission is very clear and explicit.
I also agree. In this case, the privileged action (System.getProperty)
is very concise, so the risk is very low that the additional permissions
could be abused.
