I tend to think for option 2.
Esa will lose the green mark, but over time his answer will reach a better consensus. The only problem I see is the accepted answer get almost 200 upvotes, as such Esa's answer will get low visibility at first in that question. I suggest after the move a edit to the accepted's answer, to add a footnote, to be sure to see Esa's answer for newer security's measure.
IMO, a user will see all options open that way to secure is webserver.
