I am sure people can bird on any number of cameras, I did some on my old D40 which had a fairly crude AF system for it, certainly by today's standards.
My comment is based on my experience having shot the 7D on several outings with colleagues. One of them actually dumped his 7D based largely on the autofocus system.
Do a search and you will find numerous people who complain about the 19 point system (and people thought Nikon cheaped out going with 39 on the D7000). Even simple things like the graphical focal point aid (the black box as my friend called it) is poorly done and obstrusive as they stay lit until you take your photo.
While the 7D has Canon's best DX autofocus system to date - it is not as good as the D300s, D7000 and will be leagues behind the d7100. I would note I have not tried the 7D post 2.0 firmware update so it may be better.
