Lack of SAK isn't a security issue in itself since the account or software that is able to write to the user's files must somehow be compromised. SAK is a hardening mechanism that can be employed to increase the security of a machine. Unfortunately, as implemented it is not something that we can enable by default in Ubuntu; however it would be good to have it available for those who need it. Implementing SAK in a way that works how you suggest as opposed to killing an existing X server requires work. The work is captured in our Roadmap page, which is why this bug was triaged the way it was.
