I guess this opportunity is as good as any to throw out a question for speculation. 

Why can't Canon (or any manufacturer) implement automatic MFA for any camera that has Live View?  The user would:

  • Mount the camera on a tripod or other sturdy surface
  • Point it at a standard target at some reasonable distance
  • Choose the function from the menu
  • Step back and let it go.

So how does it do its magic?  Simple: it compares Live View focus to phase detect focus, then automatically adjusts PD focus until they are the same.

Yes, there's still room for misuse by n00bs, but much less than with manual MFA.

Thoughts?

That actually sounds pretty straight forward to me, can't see why this would not be possible. Certainly a good idea!

Certainly possible, and something I'd really like to see implemented.  It's been discussed before here, and IIRC, I even suggested the possibility of a nice Canon-branded focus target.  I'm sure Canon could price a piece of plastic like that appropriately, after all, look at the reasonable prices on their lens hoods...  :o
