 o Remind user with bug script if they are missing en_US.UTF-8.

These are safe bet.

This is too invasive to locale package and may be policy violation.

Debian installer supports C.UTF-8 locale but installed Debian system..
aha. I see /usr/share/i18n/locales/C is in UTF-8 now.  POSIX and C are
different.  hmmmm

Hmmmmm interesting.  C.UTF-8 always available?  Changelog has:
 "Add patches/localedata/locale-C.diff to create a C locale." 01 May 2011 
but /usr/share/i18n/SUPPORTED does not have such locale.

I can not do dpkg-reconfigure to set system only to use C.UTF-8 by
removing all locales (C is not the choice there).  It
complains;

$ sudo dpkg-reconfigure locales
perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
        LANGUAGE = "en_US:en",
        LC_ALL = (unset),
        LANG = "en_GB.UTF-8"
    are supported and installed on your system.
perl: warning: Falling back to the standard locale ("C").
locale: Cannot set LC_CTYPE to default locale: No such file or directory
locale: Cannot set LC_MESSAGES to default locale: No such file or
directory
locale: Cannot set LC_ALL to default locale: No such file or directory
/usr/bin/locale: Cannot set LC_CTYPE to default locale: No such file or
directory

Maybe, update-locale needs some fix too. 

Can you explain how can I have C.UTF-8 locale only system?
Any place explaing C.UTF-8 (except in changelog).?

What is the difference between POSIX and C now.  What happens if LANG,
LANGUAGE, LC_ALL are  set to NULL or C. C? POSIX.  I do not see choice
between C.UTF-8, C, POSIX in locale package reconfiguration.

I see.
