Definitely removed. But you will also get moire in video shots. Moire in still shots in terrestial scenes with fine repeating patterns is less likely to occur than is often thought.

After using my Nikon D800E which has no AA filter for a while I would definitely prefer a non AA camera over an AA camera in the future.

But it does come down to your use of the camera. Some cameras are better suited for some uses than others. Much like telescopes that way.

Some cameras try to appeal to all users but in the end their is a bit of a compromise for all in that scenario.

As far as UV/IR filter goes, isn't that the culprit for reducing Ha sensitivity as DSLR UV/IR filters cut off too early and reduce Ha?
Astrodon has an article about these. He now sells his replacement UV/IR filter.

I am not 100% sure now as when I modded DSLRs it was before the dust shaker models with 2 filters.

If I were a wedding DSLR videographer I would want the AA filter for sure as moire would damage many of your scenes.
For general wedding photography it would be an issue only occassionally and I would have to test to know for sure. I have taken about 700 shots with my D800 and seen moire only about 4 times so far. So moire is clearly overrated except for video where it is a big issue.
I took a few videos of cityscapes and the moire is bad bad bad, but less so when you increase the size of the video. But video of landscape would be totally fine. Also moire is a bit weird. You can look at an image at one size and it has bad moire, you then increase the size of the image only to see no moire in the image at all. So it seems your computer monitor can show moire when there is none in the image.
