Is "ProtectHostImages" already included, just not mentioned in 1.7.1?

[bastik-1001]

The roadmap mentions "ProtectHostImages" to land in 1.7.x:

... prevent processes located outside teh sandbox from loading boxed dll's -- to enable it use "ProtectHostImages=y"

Is that already in the code for 1.7.0 or 1.7.1 and just not mention in the change-log? Or supposed to show up in a later release of the version?

Is that (ProtectHostImages=y) supposed to be the default setting at some point?

To answer my own question, this feature got delayed and landed in 1.9.0 (a pre-release at the time of writing).
