Note this bug is mentioned in the changelog for adding disco, whilst the rest of releases appear to be using https://bugs.launchpad.net/ubuntu/+source/debootstrap/+bug/1800945 bugnumber.
Adding just the symlink is not good enough for disco+ as one also needs to backport MERGED_USR=yes stanza, and/or MERGED_USR support, depending on how far back one wants to go. Otherwise, older releases will bootstrap disco non-usr-merged.
