On Fedora, /etc/X11/xinit/Xsession does:

    errfile="$HOME/.xsession-errors"
    if ( umask 077 && cp /dev/null "$errfile" 2> /dev/null ); then
        chmod 600 "$errfile"
        [ -x /sbin/restorecon ] && /sbin/restorecon $errfile
        exec > "$errfile" 2>&1

So it overwrites it without backup.  I would prefer a backup.  Perhaps I'll
file a bug...

I'm happy to have a suggestion for another key.  My one worry would be to not
use a key that is completely unique so we end up with a proliferation of
xsession error files like we already have with x2go session dirs.
