I have a 50mm F/1.8 I used it on.

It could AF on all these speeds.

So what I think this means is, it only cannot AF when the LENS ITSELF has a Maximum aperture of F8..& higher numbers

As others have said, there wasn't really any confusion to start with. The AF aperture limit only applies to the maximum wide open aperture. Although I haven't heard of any specific complaints, it could be an issue for those using a x2 TC on the EF 500mm / 600mm f/4 lenses, or (god forbid anyone actually needs 1600mm!) the 800mm f/5.6.

So no, not really an issue.
