why would you look at the whole history? Blame tells you which revision
modified the lines you are interested in. So you can jump directly to
that revision. It's annoying if this revision is just a code cleanup.

This is not an issue with GenericSetup, but if you have several release
branches, it also makes it hard to port changes from one branch to an other.

I'm not completely against code cleanups, but I don't think touching
thousands of lines just to do massive automated cleanups is the right
way to do it.
