Of course not.  The reason it has these flags is for glibc upgrading
purposes.  glibc-common rpm ships with locale-archive.tmpl file, and %post
merges all locales from that file with any possible user added locales in
locale-archive into a new locale-archive, the *.tmpl file is then deleted.

If you delete the file, you loose all localization, because we don't ship
the individual /usr/lib/locale/*_*/* locale files for space reasons.
The same effect as if you don't call setlocale at all, or just with "C" in
all apps.

That's a bad idea.
