Are all the Mannequins problems really gone for vanilla Skyrim game on latest 1.9 patch? No more possibility of duplicating or moving around?

I have vanilla Skyrim here, no DLCs.

These are from the Wiki Bugs Section without additional comments on fixes. And I can't even find Mannequin fixes on Patch Notes (http://elderscrolls.wikia.com/wiki/Patches_%28Skyrim%29, http://www.uesp.net/wiki/Skyrim:Patch). Why don't we have 1 wiki and make it good ):

• Most apparel duplication has been patched as of 1.7, however, with the Hearthfire plugin installed the first armor set placed on the mannequin in a built house may be duplicated.
• Apparel can be duplicated using mannequins. Place the apparel in the mannequin's inventory, then remove it before leaving the menu. Leave the house, re-enter, and a second set of the apparel will be on the mannequin. If the copied apparel is removed, most or all of it will duplicate again. This is one way to get multiple copies of unique armor or shields to pass on to followers.
• The first armor placed on the mannequin may stay there, even if replaced with another. This can be fixed by changing the original set in some way such as tempering the armor, or enchanting it.
• When a house with mannequins is first entered, they may be in different positions from where they are supposed to be, or armor may be invisible. They can also act like a normal person looking at you and moving its head. To fix this; either leave the house and come back or go to the mannequin's stand, activate the mannequin where it's supposed to be, and add or remove items.

• There is a possibility of mannequin movement after a "hard" save and load. (A "hard" save is when you hit "Esc">Save>New Save/Overwrite)
• The mannequins in the enchanting room may occasionally move position and appear in the middle of the basemant or elsewhere in the house
• The armor first placed on the mannequins may clone and equip itself over any other armor already on the other mannequi

• Mannequins may also "move" around the house.

They still move around.

Is item duplication completely gone at least?

Damn, haha. Would storing all my Weapons & Armor on a different house that I save help with them moving around?

Item duplication? Like when I went I my room in Dawnguard Castle and each time I "opened" the manikin, it had one more occurrence of each piece of armour in it? I don't think so...
