I would propose that this suggests that Mint as a whole ought to be based directly on Debian, or at least that LMDE ought to be the primary focus of their project. If Canonical's rampant, Unity-centered modifications place the Mint team in a situation where they must either compromise the security or stability of their users' systems, then it would seem that Ubuntu is not an ideal foundation for Linux Mint. With the rarity of major changes within Debian, and the promptness with which security vulnerabilities are addressed, it seems like an ideal foundation on which to build Linux Mint.
