If you ran that command you would break all the setuid files
(as well as just making a few files more widely accessible
than they are intended, which you noted). :)
The `rpm --restore` command might be more convenient¹. It
could be run for all the packages owning the files under
/usr/bin, something like:
find /usr/bin -type f -exec rpm -qf {} + | sort -u |
xargs -r rpm --restore
¹ Though I agree that if the system has been manually hosed
and there's any doubt about what might have been changed or
broken, a clean install would be less effort in most cases.
