I think X made this change several years/Debian distributions ago. If
you restore the facility in /etc/default/keyboard then upgrading seems
to keep your change. You have had to add it yourself when installing
afresh.

eg /etc/default/keyboard

# Check /usr/share/doc/keyboard-configuration/README.Debian for
# documentation on what to do after having modified this file.

# The following variables describe your keyboard and can have the same
# values as the XkbModel, XkbLayout, XkbVariant and XkbOptions options
# in /etc/X11/xorg.conf.

#XKBMODEL="pc105"
XKBMODEL="latitude"
XKBLAYOUT="gb"
XKBVARIANT=""
XKBOPTIONS="caps:none,compose:menu,terminate:ctrl_alt_bksp"

# If you don't want to use the XKB layout on the console, you can
# specify an alternative keymap.  Make sure it will be accessible
# before /usr is mounted.
# KMAP=/etc/console-setup/defkeymap.kmap.gz
BACKSPACE="guess"
