Here is what the managers of my two favorite 19th c./historic-themed sims--Caledon and Steelhead respectively--have to say about the recent policy thoughts from LL:
The Guvnah (via notice):
"I just don't see any changes coming to Caledon over it. We won't be flagging as 'adult' and I don't forsee any changes to anyone's usual activities.
Any goody~two~shoes snooping too closely around personal skyboxes for purposes of being the Morality Police will be reported for harrassment, let alone banned by me for unwarranted search as per our rights declarations."
Miss Tensai Hilra (via her Twitterfeed, which you may follow here):
"I dont see a huge change, our city has always been flagged as adult, and always will be. not smut, adult."
In short, do take a big breath folks.
