It's more that there's no sensible way they could do it even if they wanted to. Emulating the Windows kernel internals is well beyond the scope of what WINE is trying to do, and even if they did do it, there would be no way for the anticheat vendors to tell the difference between the AC module being sandboxed for compatibility versus sandboxed as a bypass technique. Trying to subvert the AC in any way is just begging to get banned, even if it's for beingn reasons.
