That's true, and it's intended behavior. The idea is to distinguish
between language and regional formats, and the latter variables are
considered to be part of the language option.

Yes it is. If you want the same locale for every locale category, just
make sure that you select the same locale for both language and regional
formats.

LC_ALL is typically used by coders. It's not suitable as an environment
variable on a desktop, since it makes any UI for this purpose useless.

If you want to make an exception for a particular locale category, e.g.
LC_CTYPE or LC_TIME, then set that category separately. But leave LC_ALL
unset.

It doesn't. PAM loads ~/.pam_environment at login.

Title:
  gnome-language-selector -> Regional Formats: Please indicate if it is
  overriden by LC_ALL

Status in language-selector package in Ubuntu:
  Opinion

Bug description:
  * Open gnome-language-selector, and click on the Regional Formats tab.
  * Change the value in the `Display numbers, dates and currency amounts in the usual format for:` drop-down list, say `English (Canada)`
  * Close the gnome-language-selector window.
  * Run this in a terminal: `your_locale="en_US"; sudo update-locale LANG="$your_locale".UTF-8 LANGUAGE="$your_locale" LC_ALL="$your_locale".UTF-8`
  * Log out and in from the desktop environment
  * Again, open gnome-language-selector, and click on the Regional Formats tab. As you can see, it appears like `English (Canada)` even if it is overridden by LC_ALL ("English (United States)")
