I think the method as described never really worked.

When I do as you (and the manual) suggested, I no longer
have any results for ssh host env | grep "GUILE_".

When I extend it like this it works. I include the full
paste to show that previously I had the sourcing of /etc/profile
in it:

user@shadownet ~$ cat .bashrc
# Bash initialization for interactive non-login shells and
# for remote shells (info "(bash) Bash Startup Files").

# Export 'SHELL' to child processes.  Programs such as 'screen'
# honor it and otherwise use /bin/sh.
export SHELL

if [ -n "$SSH_CLIENT" -a -z "`type -P cat`" ]
then
    # We are being invoked from a non-interactive SSH session
    # (as in "ssh host command") but 'cat' cannot be found
    # in $PATH.  Source /etc/profile so we get $PATH and other
    # essential variables.
    source /etc/profile
fi

# Adjust the prompt depending on whether we're in 'guix environment'.
if [ -n "$GUIX_ENVIRONMENT" ]
then
    PS1='\u@\h \w [env]\$ '
else
    PS1='\u@\h \w\$ '
fi
source ~/.guix-profile/etc/profile
alias ls='ls -p --color'
alias ll='ls -l'
GUILE_LOAD_COMPILED_PATH="${GUILE_LOAD_COMPILED_PATH}:/run/current-system/profile/lib/guile/2.2/site-ccache:/run/current-system/profile/share/guile/site/2.2"
GUILE_LOAD_PATH="${GUILE_LOAD_PATH}:/run/current-system/profile/share/guile/site/2.2"


I suggest that we fix the offloading documentation.
If questions are asked (I'm not the first) there are obviously problems
with how it is written.
If no one else takes on this, I will.
