Is there some way for yum to know about that?
Only if it errors out on a bad package. There have been (to my knowledge) two different types of errors. One was a truncated package on the mirrors that was damaged in transit from the build system. The other is a package that had to be rebuilt. The version numbers for packages are not changing with the fixes.
