Not all projects expect to see a/ & b/ prefix and these are configurable for a reason. Robbing the choice that has been supported for quite a long time from them is an unacceptable regression.

Why did you think this may be a good idea in the first place?

Perhaps you had configured your diff.noprefix in a wrong configuration file? This is primarily per-project choice, and your clone of git.git should not have diff.noprefix set, neither your $HOME/.gitconfig unless you always work on projects that want diff.noprefix.
