Ignored files usually are generated files (e.g. .o files) and can be safely discarded. However sometimes users may have important files in working directory, but still want a clean "git status", so they mark them as ignored files. But in this case, these files should not be overwritten without asking first.
Enable this use case with --no-overwrite-ignore, where git only sees tracked and untracked files, no ignored files. Those who mix discardable ignored files with important ones may have to sort it out themselves.
