It wasn't the statistics of internal components that were at issue. It was drivers, engineering failures, component failures, etc. Rev. B machines were re-mixed and had better, more consistent behavior. Sometimes people would wait the 18 months to get the machine with the improved stats, but the wait for Rev B phenomena wasn't predicated on that... Of course, this shouldn't surprise anyone, as when developing any new product users will find the bugs that can only be addressed in the second version. What's maybe surprising here is that Apple was cognizant enough that it withdrew the wireless charging platform before it hit the shelves.

[Besides: the iMac 'Rev A' was just a repackaging of the AIO G3 PowerMac...]
