I am not one of those who oppose or support AA in SK, just a middle man looking to provide a solution to this controversial conflict with AA. Personally, I have mine disabled because it feels more fluid and better precision is provided in various situations.
Yes, I agree to the supporters that it's useful for users of controllers and those with bad connections. However, I also agree with those who oppose as it does make many of those who use it too much cheat to the top.

With all these verbal wars in the forums between the players who support AA and those who oppose it, how about changing the LD server configurations to please both parties, by creating 2 new lobby categories: Hardcore LD for both PvP and GvG. It seems Feyi-Feyi had the basics of this idea in a previous forum post, but here is what I propose as how both PvP and GvG LD would be split:

1) Traditional LD: AA is available and can be toggled on or off, as it is currently. Perfect for players or guilds new to LD, those with bad connections, and those who feel uneasy about running a match without AA.
2) Hardcore LD: AA is disabled by default and cannot be enabled. Perfect for players who prefer a better challenge, or those who oppose facing AA users in the traditional lobbies. A true test for the LD Elite.

These changes would also provide separate LD rankings for both Traditional and Hardcore, so you'll know who has scored the most points in either category.
However I cannot guarantee this will solve the problem on the side of new LD players and those who cannot play without AA, I do understand the possibility of 1 or both scenarios could result in this:

1) Veteran LD players who are tired facing AA users will leave for Hardcore LD, which may result in a more balanced LD for the rest of the players who had struggled in the past.
2) Experienced LD players who enjoy slaughtering "Noobs" for fun may end up continuing to use Traditional LD and could be declared as trolls by inexperienced players who are struggling to lay a hand on those veterans in the Traditional LD lobbies, which wouldn't be good for those who were hoping Hardcore LD would alleviate the threat of a 10-20k LD players beating them constantly or spawn-camping for kills.

I am not sure if OOO will get this idea, but I cannot predict the future anyways. Who knows if a "Coliseum Update" eventually gets created and ends up doing just that. We'll just see if it possibly happens in the next few years, more or less. All I know is OOO will certainly keep AA around for the unforeseen future.
