I'm still not sure what a huge benefit eye af is. How hard is it to move a focus point onto an eye?
Imagine little kids running helter-skelter all over a playground ..... climbing up the ladder, then "whooshing" down the sliding board ...... then dashing over to the rope swing ....... then going round and round as fast as they can on the merry-go-round.
If you want to track this action from a bit of a distance with a long telephoto, and keep the kid's face filling the frame, then how would you ever make sure that perfect focus on the kid's eye is maintained at all moments, unless you had eye autofocus? . Do you actually think that you would be able to do this perfectly, without the aid of eye autofocus? . If so, then you are a spectacular individual with otherworldly hand-eye coordination.
Or, if you don't shoot running kids, then think of sports photography. . Imagine a tennis player running and dashing wildly about the court, and you standing there trying to get a close-up of his facial expression as he is playing. . How would you do that if you had to move the focus point manually? . As soon as you adjusted your focus point selection, he would be out of the frame and you would have to try to find him in the viewfinder and change the point again and reacquire focus on his eye ........ can you even imagine how impossible it would be to capture perfectly focused face closeups in such a situation if you didn't have eye autofocus?
Sadly, this technology only seems to work on human eyes at this time. . If it ever gets to the point where it could be used on ANY moving object (user programmable), then it would revolutionize wildlife photography for me.

And yes having to move focus point during something as dynamic as a wedding .....
That is actually kind of funny, when you compare it to the two types of scenarios that I described above.
A wedding, dynamic? . Compared to what? . They don't even run at weddings - the quickest movement there is is when they walk briskly down the aisle or when the girls step forward to catch the bouquet. . Compared to the all-out running and leaping you have in sports, or birds in full flight, that doesn't seem dynamic at all.
"Your" and "you're" are different words with completely different meanings - please use the correct one.
"They're", "their", and "there" are different words with completely different meanings - please use the correct one.
"Fare" and "fair" are different words with completely different meanings - please use the correct one. The proper expression is "moot point", NOT "mute point".
