The absolute units of the misalignment don't matter. I.e. if it's 0.1mm or 0.05mm, does not matter. (That can't easily be measured anyway).
It is true that retrofocus lenses tend to have more sensitive tolerances than e.g. a double gauss or a sonnar, but if it can be built within the tolerances it doesn't matter.
The first three lenses tested for micro four thirds were the panasonic 42.5/1.2, voigtlander 42.5/0.95, and voigtlander 17.5/0.95. The voigtlander lenses are excellent with respect to consistency, and the panasonic lens is among if not the worst I have ever seen.
